CONTEXT
3
Detailed context for this study is provided in the Inception report and is not repeated here. It is sufficient
to note that this study is a part of the Water Management and Development project (WMDP).
1.1.1
The Water Management and Development project (WMDP)
Implementation of the Water Management and Development Project (WMDP) was approved in June,
2012 and is due to run through to the end of 2018. The project is supported by the World Bank and its
development objectives are to improve water resources planning, management and development, and
access to water and sanitation services in priority areas. The project’s broader objective is to improve
integrated water resources planning, management, and development. In addition, it aims to protect
water resources, conserve the environment, and improve productivity through better management of
water for livestock, irrigation, and energy.
The project covers five main themes:
 Water resource management
 Urban services and housing for the poor
 Rural services and infrastructure
 Pollution management and environmental health
 Other environment and natural resources management
Significantly, the first of these attracts nearly half of the available funding, which should ensure a major
boost to the advancement of water resources management in Uganda.
The WMDP aims to support the Government of Uganda’s efforts to implement planned IWRM reforms
by creating the analytical, infrastructural and institutional platform to improve water resource
management, productivity and service delivery, and to reduce vulnerability to water shocks. These
priorities are aligned with the two key pillars of the Africa Strategy namely:
 to create opportunities for growth; and
 address vulnerability and resilience.
The project has been informed by the key recommendations of the UWCAS 1. It takes a pragmatic and
phased approach by addressing urgent infrastructure needs that depend on better water resource
management, while also supporting the operationalization of planning, management and
development capacity at the WMZ level in order to ensure long-term sustainability.
The WMDP comprises the following components:
 Component 1 - Investment in Integrated Water Resources Development and Management
 Component 2: Infrastructure Investments in Urban Water Supply and Sanitation/Sewerage and
Catchment/Source Protection
 Component 3: Strengthening Institutions for Effective Project Implementation
Component 1 includes sub-components:
 Sub-component 1.1: Identification, preparation and implementation of selected priority
investments through a participatory planning process in the Kyoga and Upper Nile WMZs

Improvement of the national water resources monitoring and information system
1.1.2
This Study
The study was kicked off at a meeting on 3 March 2015 and this marked the start of the Inception Phase.
The Inception Report was presented to stakeholders on 2 April 2015.
The objectives of the study are
 Strengthening and upgrading the existing surface and ground water, meteorological, and water
quality and pollution monitoring network and associated information system.
 Designing and developing a water information system to include the hydrological information
system, spatial data system (GIS etc.), information management system (hydrologic design aids
etc.), knowledge management system (DSS etc.), and data dissemination system (on line/web
portal etc.)
The objectives of the Consultancy are to:
 design a comprehensive Water Information System (WIS),
 recommend an implementation road map;
 develop a strategy for its effective utilization and sustainability.
The end of the Inception Phase marked the start of the Interim Phase, which had as its objective to
provide guidelines for moving forward into the design phase. These guidelines were aimed at ensuring
that the designed WIS ultimately satisfies the needs of its users. The draft Interim report was presented
in two successive drafts. The first draft was presented at a stakeholder workshop on 20 August 2015.
Significant re-drafting of the report was carried out and a revised version submitted to the Client in
February 2016.
The Interim Phase is followed by the Design Phase of which this report forms the second part. The first
part provided the System Requirement Specifications and these were covered in the previous report.
This report is aimed at providing the design details and specifications of all elements of the WIS so that
implementation can proceed rapidly at the end of this study. Outputs also include the necessary
procurement documents, a (phased) implementation plan and a training plan.
The main steps of the study and the interrelationships are shown in Figure 1-1.

2.3 HIS DESIGN AND SPECIFICATIONS – SURFACE AND
GROUNDWATER MONITORING EQUIPMENT
2.3.1
Introduction
As presented and summarised in the Interim Report there are a number of ongoing projects focussed
on rehabilitation of the hydrometric network. It has been assumed that around 45 stations will be properly
handled under these initiatives. Under this component of this it is assumed that rehabilitation and even
expansion of the network eventually will continue in Phase 2 at the rate of:
 2 surface water stations rehabilitated/upgraded per year per WMZ
 2 groundwater stations rehabilitated/upgraded per year per WMZ
The HIS component of the project thus allows for the gradual rehabilitation/upgrading of the remaining
(i.e. in addition to the other ongoing initiatives) stations at the rate of +/-8 stations per year (2 per WMZ),
but only in Phase 2 of the project. No funds have been allocated to Phase 12 for the supply and
implementation of surface and groundwater monitroing equipment.
This should be an ongoing initiative and assumes that once all stations are “upgraded/rehabilitated”
there will be further ones which qualify for a new rehabilitation.
2.3.2
Climate
For all climate data collection and processing the standards as laid out by UNMA will be followed. The
purchase of climate stations is not foreseen as part of the project. UNMA is engaged in a process which
is aimed at rapid expansion of their network, which may satisfy the requirements of the HIS.
2.3.3
Surface Water and Groundwater Monitoring
2.3.3.1 Introduction
In this section of the report the design specifications for the installations and equipment required for the
acquisition and transmission of data from the following type of monitoring stations are presented.
 Lakeshore stations measuring the water levels of lakes (man-made and natural)
 River gauging stations measuring the water level at a specific site
 Groundwater level stations, measuring the water level in a borehole.
The specifications for a range of other specialized installations and/or equipment are also provided.
These include:
 For measurement of discharge on rivers:
 Current meters and ancillary equipment
 Acoustic Doppler current meters (ADCP) and associated equipment
 Specialised/specific surveying equipment
WIS Design and Operationalisation Report
Ministry of Water and Environment

2.3.3.2 Lakeshore stations
2.3.3.2.1
General specifications
Recording the water level of a lake may only be required for knowledge of the storage within the
lake, but more significantly this data can provide a record of lake inflow and, for an uncontrolled
lake, outflow. Operating a lake or reservoir water level recorder properly requires consideration of
wind effects, seiche and rating curve uncertainties. If an unregulated lake has a stable threshold
across its outlet, the outflow can be gauged and rated against lake level.
For the rehabilitation of existing stations, the specifications provided relate mainly to the provision of
specialist equipment. In the case of new stations some specifications relating to site selection are also
provided.
For new lakeshore stations the following aspects shall be taken into account when selecting a lakeshore
water level monitoring site:
 Access and Legal Requirements. The following issues concerning access are to be taken into
account:
 Safe, all weather access over the full anticipated range to be measured
 The ability to position machinery and materials during construction
 A long-term access agreement with any landowners whose land must be crossed to gain
access to the site
 Environmental impacts
 Hydraulic Properties. The following specific lake properties are to be taken into account:
 When outflow measurement is required, the site should be located near to the outlet, but away
from any drawdown effects
 The measuring location should be sheltered from waves. This avoids surging at the sensor,
erosion, dampness and physical damage. In reservoirs, waves can cause an unmeasured loss
of water over a dam that may, at times, be significant.
 How to get an intake or sensor to record the lowest possible level Often lakes have shallow
edges and long intakes or sensor cables may be required.
2.3.3.2.2
Gauge Plates (staff gauges)
GENERAL
The minimum installation for the measurement of water levels is the gauge plate (staff gauge) installation
together with its accessories. In general, the gauge plates shall be used for spot measurements, either
alone or in support of an automated measurement.
INSTALLATION
The gauge plates are to be installed vertically, either in a continuous set on a vertical wall and covering
the full range of possible water levels, or as a number of individual gauge plates, each one mounted on
a separate support and measuring a part of the full range. A combination of the two is also possible.
Staff gauges shall be installed so that:
 the zero of the set of gauge plates is at the recording zero. The recording zero level should be
below the lowest possible water-level, given that the bed may degrade significantly over the life
of the station.
 the staff gauge supports are immovable and not prone to settling
 the water level can be easily and accurately read at any time
WIS Design and Operationalisation Report
Ministry of Water and Environment
16
 the gauge plates are protected from high velocities. If high velocities are unavoidable, keep each
gauge short in length (1m) and have more of them or have the full set fixed to a concrete face
which may be possible in a reservoir.
 The installation should include two very solid benchmarks above the high flood level so that if the
gauge plates are disturbed or destroyed they can be put back at the correct levels.
The staff gauge may be supported by a concrete or steel pole of sufficient length for stable
installation on water banks and riverbeds. The pole shall have provisions to rigidly attach the staff
gauges and a provision to adjust the staff gauges to the required elevation. The concrete (or steel)
pole shall have such solidity that it can permanently sustain partial and/or full immersion in water
and resist to any kind of water transported debris.
GAUGE PLATE SPECIFICATIONS
These environmentally rugged iron gauges are finished with a special porcelain enamel to ensure easy
reading and resistance to rust or discoloration. They should virtually never need replacement under
normal conditions.
Full details are presented in Annex 1-B.
INSTALLATION AND CIVIL WORKS
Two kinds of installation can be considered. The preferred is the use of an existing permanent support
(pile of bridge, wall, etc.). The second one is the concrete pillars. If the cross section is too large (big
rivers, lakes), or if there is no concrete or rock support, these concrete supports can be constructed.
The inconvenient is the cost but the advantage is an easy reading of the gauge plate
Full details are presented in Annex 1-B.
Typical installations of this type are shown Figure 2-3. If a concrete support of this nature is not possible,
a steel post can be used, but the stability must be assured.

Automatic water level recording station
2.3.3.2.3.1
General
An automatic recording station for a lake or reservoir can be broken up into the following components:
 Sensors
 Data Collection Platform (DCP) and logging devices
 Civil works and ancillary works
The specifications for these components are provided in the following paragraphs. It should be noted
that at all automatic water level recording stations there will be a complete gauge plate installation
according the specifications already provided under 2.3.3.2.2.
2.3.3.2.3.2
Sensors
GENERAL
As indicated in the Interim Report the water level sensor will be either a radar sensor or a pressure
transducer. If the installation of a radar sensor is feasible this should be preferred. The sensor is to be
connected to a data logger for automatic data storage and transmission (data collection platform).
The output signals for each sensor are to be selected from the commonly available formats, such as 420 mA, 0-10VDC, SDI-12, RS-485). The electrical power for the sensors and data logger is to be nominal
12 VDC. The power consumption of the sensors is to be compatible with the power availability of the
power supply system of the station with 20% reserve.
RADAR SENSOR
General
The radar sensor shall be capable of measuring water
levels from 0.5 metre to 35 metres (for higher measuring
ranges up to 75 metre, a pressure transducer will be
used or a specific radar as VEGA model).
As the sensor shall be installed on a mast or a kind of
gallows, it must be suitably protected against lightning.
Sensor housing
The sensor housing must be robust, corrosion resistant,
resistant to ultra-violet rays, insensitive to vibration and be water and dust protected to comply with
rating IP68 as defined in IEC144.
Full details are presented in Annex 1-B.
Measuring sensor
The sensor must have a standard resolution of 1 mm and an accuracy of +- 1 cm or better over the full
measuring range and should have a measuring interval of at least 60 seconds.
Full details are presented in Annex 1-B.
Data transmission cable, power supply, measuring accuracy and output signal
Full details are presented in Annex 1-B.

Installation
Figure 2-4: Installation of radar sensor
Considering the radar footprint and the safety zone (2.5 meters), the radar sensor shall be installed on
a horizontal jib and a pole with provisions to rigidly attach the structure. It must be supported by a
concrete structure for stable installation. The sensor signal angle depends of the manufacturer (total
angle = 10° to 20°).

Ministry of Water and Environment
Installation details are provided in Annex 1-B.
PRESSURE TRANSDUCER SENSOR
General
This kind of sensor will be proposed if radar sensor cannot be installed. Pressure transducers must be
capable of measuring water levels between 0 and 100 metres (or more) using a barometric pressure
compensation.
The pressure transducers must be highly reliable and ensure a wide range of application for measuring
pressure in all fields of water level measurement.
Transducers must be suitably protected against lightning, and test results must be available upon
request.
Where applicable, the temperature measurement and conductivity can be included with the water level
sensor.
Sensor housing
The transducer housing must be robust, corrosion-resistant, insensitive to impact and vibration and
watertight up to at least 100 metres of water column.
Full details are presented the tender document in Annex 1-B.
Measuring sensor and transducer cable
The measuring cell must be chemically and thermally resistant and must operate using the piezoresistive
method. The pressure sensor shall be designed and calibrated to function satisfactorily under a
temperature range of -5°C to +45°C and shall have a built-in temperature compensator.
Full details on the sensor and transducer cable requirement are presented in the tender document in
Annex 1-B.
Data transmission cable
Immerged water pressure devices utilize a vent tube in the cable to allow the device to reference
atmospheric pressure. The resulting gauge pressure measurement reflects only the depth of
submergence. When using absolute devices, the pressure measurement reflects the depth plus the
atmospheric pressure. This atmospheric pressure must be then subtracted from the absolute pressure
to give the actual pressure due to depth.
Power supply
Full details are presented in the tender document in Annex 1-B.
Measuring accuracy and frequency
The overall measuring accuracy of the pressure transducer must be better than or equal to 0.1 per cent
of the full scale. The water level measurement frequency will be every 5 minutes to several hours,
depending of the level variations. The switch from a frequency to another one will be locally determined
by the Data Collection Platform.
WIS Design and Operationalisation Report
Ministry of Water and Environment
21
Civil works and installation
The immersed sensor should be inserted in a vertical stand-pipe (stilling well) installed adjacent to a
lake or reservoir bank or a river. This pipe will be in galvanised steel with a diameter of 1’1/2 or 2” max.
At the top, a steel box is installed for the maintenance access.
At the other extremity, the well will be drilled for a better flow circulation.
For the river stations the same protection can be used, but the fixation quality depends of the support
and/or the water velocity capability. For Lakes we can build a concrete or steel housing to install inside
the steel cabinet for instrumentation. Concrete is better for protection but it is more expansive.
Full details are presented in the tender document in Annex 1-B.

General
This kind of sensor will be proposed for all groundwater stations. Pressure transducers must be capable
of measuring water levels between 0 and 100 meters using a barometric pressure compensation and
300 m of cable for the depth,
The pressure transducers must be highly reliable and ensure a wide range of application for measuring

method.
Further details on the sensor and the transducer cable are presented in the tender document in Annex
1-B.
Data transmission cable
Immerged water pressure devices utilize a vent tube in the cable to allow the device to reference
atmospheric pressure. The resulting gauge pressure measurement reflects only the depth of

IMPLEMENTATION OF THE WIS
3.1 INTRODUCTION
Implementation of the WIS is a major undertaking and will require that those person(s) supervising the
implementation have a clear idea of the overall concept and the main design principles. In this short
chapter of the report the main implementation principles are presented in the Implementation Strategy
and a phased implementation plan is then presented. The current phase of the WMDP runs through to
the end of 2018 and this has between the end of this study and the end of 2018 is taken to correspond
to Phase 1 of WIS implementation.
3.2 IMPLEMENTATION STRATEGY
3.2.1
Introduction
The strategy for implementation is defined by a number of key principles including:
 A phased approach, but one that will allow all aspects of the operational WIS to be demonstrated
during Phase 1 and for a large number of key water-related databases to be integrated into the
system Phased approach is supported by a modular approach which allows for lessons learned
to be transformed into improved implementation
 Institutional strengthening, including an adequately resourced WIS Management team
 Implementation must include a wide range of training programmes
 Implementation to be supported by a communication strategy aimed at promoting the existence
and importance of the WIS to a wide range of stakeholders.
 Monitoring and evaluation framework aimed at ensuring the success of the WIS
 Implementation to be closely supervised by one team throughout Phase 1.
3.2.2
Phased approach, fully operational WIS
Within the time frame of the remainder of the WDMP, only a certain amount can be achieved. Different
options for phasing have been considered including focussing only on the HIS countrywide (all four
WMZs) during Phase 1 and then the overall WIS in a subsequent Phase. However, it has been agreed
that it is important to be able to demonstrate a “fully operational” WIS by the end of Phase 1. This means
that, while fully operational, the WIS would not be complete. To be fully operational:
 A number of the water-related databases are to be connected to the central WIS system. It has
been agreed that these should include the six (6) databases under the control of DWD, the
national level databases under DWRM Headquarters and the databases under the control of one
the Water Management Zones (WMZ).
 For the selected WMZ, the entire HIS will be implemented, meaning as from data collection
through data processing to storage on the relevant database.
 The overall WIS portal is to be fully operational
 The spatial data system should be fully operational

The goal of phase 1, then is that full functionality of the WIS can be demonstrated including the collection
and processing of the data that feeds into one of the HIS databases at the WMZ level. It will also be an
opportunity to learn lessons so that the addition of the remaining WMZ HIS and further water-related
databases outside MWE/DWD can be facilitated in the second phase of implementation.
WIS Design and Operationalisation Report
Ministry of Water and Environment
3.2.3

Modular approach and experience sharing
Linked to the phased approach is the concept of a modular approach. Phase 1 will demonstrate how a
WMZ HIS is to be incorporated into the WIS and the steps that have to be followed. Replication for the
other WMZ should be straightforward. Similarly, steps required to incorporate a water-related database
will be demonstrated during Phase 1.
3.2.4
Institutional strengthening
Implementation and operationalisation of the WIS will require the setting up of a WIS management team.
Details are provided in the section on institutional strengthening. However, from the implementation
perspective, it is important that this team is identified right at the beginning of the implementation process
so that they are involved in all aspects of implementation including:

Supervision of the successful tenderer and the development of a close working relationship to
ensure that the Client’s needs are met and that fine-tuning can be achieved to ensure the best
possible end-product

To be capacitated through close working relationship with the successful tenderer and to be a
part of the various training programmes.

To ensure that the WIS management team is in position to independently manage all aspects
of the WIS by the end of Phase 1.
3.2.5
Capacity building
A wide range of capacity building is proposed and should be supplied as part of the tender. It is strongly
recommended that the organisation implementing the various parts of the WIS is also responsible for
providing the training at all levels. See also Section 3.2.8 below.
3.2.6
Promotion of the WIS
The sustainability of the WIS will be greatly supported if can be demonstrated that is being used and
serving a purpose for a wide range of stakeholders. Promotion of the WIS is therefore an essential part
of implementation. As a first step, key institutional stakeholders in the public and private sector should
be targeted because their buy in is essential in making the WIS the accepted standard across the water
sector. As a second step, once the WIS is really operational it should be made as accessible as possible
to the general public. The more of a national institution that the WIS becomes, the more its sustainability
is assured.
3.2.7
Monitoring and evaluation
The tenderer should set up a monitoring and evaluation system to be implemented during Phase 1. It is
important that the successes and failings of the WIS in realising its objectives are monitored and
evaluated so that corrective actions can be put in place.
3.2.8
One Implementation Team
Implementation of the WIS requires a wide range of expertise as shown in the different sections of
Chapter 2. It is unlikely that a single company will have the full range of required experience and
expertise available within their organisation. Given the interconnected nature of the different
components of the WIS and the associated capacity building its strongly recommended that the
implementation of Phase 1 should be supervised by a suitably qualified Experts who fully understand all
aspects of the WIS to be implemented. These experts should work closely with the WIS Management
Team (see Section 4) and would be responsible for:

PLAN FOR OPERATIONALISATION OF THE WIS
4.1 INTRODUCTION
The key areas for ensuring the operationalisation of the WIS include:
 Institutional strengthening
 Monitoring and evaluation and
 Capacity-building
4.2 INSTITUTIONAL STRENGTHENING
4.2.1
WIS Management Team
The WIS, implemented as proposed in this study, has to be considered as something new and additional
to what exists at present. While Phase 1 will see limited coverage of the water sector, by the end of
Phase 2, the WIS should be widely implemented and used across the water sector. As such, it is clear
that the WIS requires a dedicated management team both during implementation and operation.
The WIS Management Team could be part of the DWRM in Entebbe. This is effectively in line with the
recommendations of the Operationalising Catchment-based Water Resources Report (COWI, 2010),
which stated that “it will thus be important to not only improve access to the requisite information, but
also to build data management and information sharing protocols into the institutional structures
between the DWRM, its institutional partners and stakeholders”. The WIS management team could also
sit within the DWD or elsewhere within MWE.
The following three posts should be operational:
 WIS Manager. This should be someone with extensive experience in the water sector, an
excellent understanding of catchment-based water resources management and IWRM and of
information systems
 WIS IT expert. This person should be an IT expert with an excellent understanding of information
systems, hardware, software, communications and web-based systems
 Communications specialist. In view of the proposed role of the WIS and the need to get it widely
used and accessible, there is a need for a communications specialist with experience in webbased applications and development communication to be part of the team.
It is important that these positions are made operational at or before implementation of Phase 1 of the
WIS so that they can play a key role in managing the implementation process and at the same time
benefitting from the proposed training sessions.
4.2.2
Capacity at WMZ level
The proposed functions at the WMZ level have been defined in the Operationalising Catchment-based
Water Resources Report (COWI, 2010). They include:
 Zonal water resources monitoring data collection, storage and transfer, as well as information
dissemination
 Zonal water resources mapping, assessment and planning
 Regional water quality laboratory
WIS Design and Operationalisation Report
Ministry of Water and Environment
48
 Contribution to national and international assessments and planning including EIAs
 Permits applications and assessments
 Compliance monitoring
 Technical assistance and facilitation to relevant stakeholders
 Contribution to national planning and coordination etc.
The proposed staffing structure for each WMZ office, as per the recommendations of the
Operationalising Catchment-based Water Resources Report (COWI, 2010) are shown in Figure 4-1.
The functions of the different units entirely reflect the proposed implementation and operationalisation
of the WIs, and in particular the HIS:
 For water resources regulation the WMZ will lead in regional level (catchment and WMZ) water
use regulation, planning and implementation of policies and strategies as well as contributing to
national level activities. It will assess, review and make recommendations to the centre on permits
applications.
 For water resources monitoring and assessment, the relevant unit, headed by a principal water
officer will:
 Supervise data collection and take responsibility for regional level water resources
assessment, modelling and forecasting
 Have oversight over the “WRMAIS” (effectively the HIS), including the update and
maintenance of databases
 Regional level hydrological data and information management and exchange
 Development and maintenance of the hydrological monitoring network
 For water quality management, the relevant unit, headed by a principal water officer, will take
charge of regional level water quality and pollution monitoring, assessment and implementation
of related policies and strategies,
 Support permit assessments, especially discharge permits and EIA reviews,
 Operations of the regional laboratory for water and environmental quality analysis etc.
The proposed responsibilities for HIS implementation as put forward in this project are perfectly in line
with these stated functions. The proposed staffing of 21 technical staff and 11 support staff are
considered sufficient to fully carry out the required functions. The institutional structure is therefore
adequate and does not require any strengthening. However, the current challenge lies in the fact that
the WMZs are not yet fully staffed. In view of the proposal to operationalise only one of the WMZs during
Phase 1 of implementation, it is recommended that all efforts be made to make the structure of this
WMZ as complete as possible. Phase 1 of the proposed implementation schedule will ensure that
adequate training and capacity building is provided.

4.3 MONITORING AND EVALUATION
4.3.1
Introduction
During the course of Phase 1 a monitoring and evaluation system is to be set up and tested. The aim of
the system is to evaluate whether the proposed WIS system is achieving its purpose and whether
adjustments of the design and implementation schedule have to be made.
Figure 4-2 summarises the monitoring and evaluation process.
Figure 4-2: Monitoring and Evaluation Framework for WIS
4.3.2
Baseline and Targets
At the beginning of implementation, it will be necessary to establish the current status in a number of
areas related to the availability and sharing of water-related information. The status of data collection
networks will also have to be established. This was done during the first step of this consultancy but the
information will have to be updated, especially in view of ongoing projects to improve the hydrological
monitoring networks etc.
In consultation with the Client, those responsible for implementation of the WIS will develop a set of
targets related to the objectives of the WIS and define measurable indicators that can be used to
measure progress towards the achievement of these targets
4.3.3
Implementation of Monitoring and Evaluation framework
The monitoring and evaluation framework should be developed during the first six months of the project
so that the impacts of the project can be measured during both Phase 1 and Phase 2. Terms of reference
for the development of the monitoring and Evaluation framework are provided in the annex.

4.4 TRAINING PLAN
4.4.1
Introduction
The training plan covers the capacity building requirements during Phase 1. Training will fully involve all
those key players associated with the integration of the water-related databases to be included as part
of Phase 1.
Given that the HIS will only be implemented at one WMZ during Phase 1, training will only be provided
for all concerned personnel at this one WMZ. However, it has been assumed that two persons from
each of the other three WMZs, as well as headquarters, will attend these training sessions.
The preliminary schedule of training indicated on the Implementation schedule.
It is suggested that training will be organized according to the categories of users: IT expert and system
administration, SDS staff, WIS and HIS users and external users. The overall training plan is subdivided
as follows:
 WIS Infrastructure Administration and related Strengthening of Technical Capacity
 WIS Portal
 Spatial Data System
 HDA and DSS
 WMZ-based training
The term of reference for the provision of training are provided as Annex 1-D.

4.4.5 Training on Hydrological Design Aids (HDAs) and Decision
Support Systems (DSS)
4.4.5.1 Introduction and Objectives of training
The objective of the training sessions is to strengthen capacity in the use of hydrological design aids
and decision support systems.
It is proposed to organize the training on HDAs and DSS in 4 parts.
WIS Design and Operationalisation Report
Ministry of Water and Environment
55
 Part 1: HAD/DSS tools in the Nile DSS: The first part of the proposed training will focus on the
HDA tools provided by Nile DSS. The training sessions will be organised following the
implementation of the WIS Portal and particularly after the implementation and commissioning of
the interface between the Nile DSS and the SOS times series dissemination service.
 Part 2: Lower complexity HDAs: The second part will focus on the HDAs which are considered
to be of low complexity and which could be implemented in the short term. This includes the
following tools:
 Intensity-Duration-Frequency (IDF) curves
 Estimating potential evaporation
 Design floods
 Estimating groundwater recharge
 Estimating base flow and flow analysis
It is considered that the required data will be available from the HIS monitoring networks. It is
therefore planned to schedule it immediately following the WIS portal implementation and after
the supply of the required HAD tools.
 Part 3: Medium complexity HDAs: The third part if the training will be devoted HDAs with a
medium level of complexity. It will be organized at the end of Phase 1 and will cover:
 Assessment of water quality, ecological state and trends
 Part 4: Remaining HAD/DSS tools
The fourth part of training will be engaged in the second phase of the implementation. Many of the
remaining tools are classifies as complex in the WIS System Requirement Specifications Report.
4.4.5.2 Proposed Participants
It has been assumed that the training sessions will include hydrologists at the WMZ and level and from
headquarters. It is also important to include hydrologist and engineers from other institutions who use
HDAs on a regular basis (e.g. Ministry of transport). Allowance is made for 10-15 participants depending
on the training area.

2.2.14 Sediment water quality samplers or Turbidity
We can approach the sediment measure, by sampling or by measuring the turbidity.
In the first case the methodology is complicated to manage, but the precision is better. We measure all
kind sediments. If we want following the evolution of the sediment, it is necessary to organize several
campaigns in different hydrological conditions.
With the Turbidity sensor, we measure only the suspended sediments, but we have an automatic
continuous record. By calculation and laboratory analysis after sampling, we get a correspondence
between the turbidity and the suspended sediment. Sediment and water quality that may be sampled
using approved equipment is divided into three categories depending on its location in the stream.
WATER QUALITY SAMPLERS
 Suspended sediment is sediment that is carried in suspension in the flow of a stream for
appreciable lengths of time, being kept in this state by the upward components of flow turbulence
or by Brownian motion5.
 Bedload is defined as that part of the sedimentary load of the stream which is moving in almost
continuous contact with the stream bed, being rolled or pushed along the bottom by the tractive
force of the moving water.The mechanisms by which it moves can be varied and complex.
 Bed material is sediment in the streambed that is at rest, but may re-suspend and move as coarse
suspended sediment or move as bedload.
Different equipments could be selected:
 For Suspended-Sediment Sampling (and quality),

The sampler has a streamlined cast aluminium body 28 in long that weighs 41 lbs. It has tail fins to orient
the sampler so that the intake nozzle in the head points directly into the approaching flow. The sampler
head is hinged to provide access to the pint or quart bottle sample container located in a cavity in the
sampler body. An exhaust port pointing downstream on the side of the sampler head permits escape of
air from the sampler container as it is displaced by the sample being collected. The sampler uses a 3/16in internal diameter nozzle and can be used in stream velocities ranging from 1.5 to 5.3 ft/sec. It can be
used to a depth of 72 ft with a pint container and 51 ft with a quart container.

of material from the bed of a shallow stream. The overall length of the tubular sampler is 46 in and it
weighs 7.5 lbs. The lower end of the sampler contains a 2-in diameter, 8 in long cylinder that is pressed
into the stream bed to collect the sample. A handle for pressing the cylinder into the bed is on the upper
end, and passes through the sampler frame to the piston inside. The suction created by the piston holds
the sample in the cylinder. The sample is pushed out of the cylinder by the piston.
US BLH 84(OR SIMILAR)
This is a wading-type hand-held bed load sampler. The sampler consists of an expanding nozzle, a
sample bag, and a wading rod assembly. The sampler design enables collection of particle sizes larger

 set of samples and store at set intervals. Minimum of five seconds and a maximum of 24 hours
for intervals of sampling and storing.
 Delta recording for water levels -Compare measured value with previous stored value at set time
intervals. If new value differs from the pre-set difference, it must be stored, in addition to the last
value. If not, the value must be ignored. Wait for next time interval.
