INTRODUCTION
The HydroTab consists of software developed and supported by Hydrological Services
combined with the respected “Samsung Galaxy Tab Active” hardware (Model SM-T360),
especially designed for harsh environments and use by tradepersons.
The Tablet communicates via Bluetooth to the Hydrological Services’ CMCsp, PVD100,
PVD200 and MAG1 Current Meter Counters.
Direct water velocity measurements may be taken, or full river gauging data may be collected,
calculated, displayed and emailed back to the office.

MAINTAINENCE
The HydroTab does not require much maintenance, but a few simple precautions will
ensure a long life for this product.
2.1
Connector / Socket Care
The Galaxy Tab Active is
submersible to 1m for 30 minutes.
If the device is accidentally dropped
into the water, remove quickly,
switch it off and dry with a soft
absorbent towel. Make sure the
connector sockets are free from
water, dust and dirt before plugging
in the charging lead.
2.2
Battery Care
The Galaxy Tab Active contains a rechargeable 4.45Ah
battery which can be recharged via a standard 5V USB
wall or car charger. This battery is also replaceable.
2.3
Touchscreen Care
The touchscreen of the Galaxy Tab Active is a capacitive type, and may be damaged if
not treated with a little care.

DO NOT use a ball point pen or pencil or sharp object to touch the screen.

DO NOT use excessive pressure when touching the screen.
A very light finger pressure is all that is required to perform a touch – or the supplied
touchpen may be used.

OPERATION
Once the Tablet is awake, the HydroTab Application is started by pressing the HS icon in the
Home screen. The application operates in Portrait mode. In addition to the LCD being “sunlight
readable”, most screens have been created using black text on a white background, with a large
text size to make it more easily readable when in the field.
Power On

Gauging
The gauging part of the Application provides a structure to manage the gauging data.
Gauging sites are created, with information to define the site – such as site ID, location
description, GPS co-ordinates, special notes, and a photograph. Multiple gaugings are
then performed at each site over time, building up historical snapshots at that site.
*** NOTE ***
It is up to the operator to create “Site Names” that reflect the exact location of the site.
Some organisations use an ID number to identify the sites, some use the name descriptor
and some use a combination of both. For example :
Site Name = GeorgesRiver
Site Name = GeorgesRiv_PleasurePt
Site Name = GeorgesRiver_12345
Site Name = 12345
or

Security / Warranty
The HydroTab Application is loaded onto the Samsung Tab Active by Hydrological
Services – where a security key is generated for each specific tablet. This ensures the
Application is compatible with, and has been tested on each device and has passed our
Quality Assurance.
Please note :

The Application will not run on user provided android tablets or phones !

The Samsung Tab Active has the standard Samsung warranty.

Loading 3rd party Applications onto the tablet may introduce virus’ and void the
Hydrological Services warranty – and is therefore strongly discouraged.

Appendix C Discharge Calculation Methods
In both methods the mean water velocity in each vertical is calculated by using the weighting
table shown in Appendix A. For example, if 3 water velocities are measured in a single
vertical, they would be measured at depths of 0.2D, 0.6D and 0.8D. The mean velocity of this
vertical would therefore be :
Vmean = (V0.2D x 0.25) + (V0.6D x 0.50) + (V0.8D x 0.25)
The following sketch shows a typical discharge with depth measurements d0, d1, d2, d3, …
taken at each vertical (note d0 is the depth at the bank, usually zero, but may be non zero) – and
the distance between the verticals b0, b1, b2, b3,…..calculated from the distance from the
reference point - and the mean water velocity v1, v2, v3, …. calculated for each vertical.
These measurements are then used to calculate the discharge using either the Mean Section
method or the Mid Section method.
*** PLEASE NOTE ***
Each method will yield slightly different results, as described on the following pages.

Mean Section Method (From Australian Standard AS3778.3.1 ISO 748)
The cross section is regarded as being made up of a number of segments, each bounded by
two adjacent verticals as shown in the following diagram.
The discharge of each segment is calculated as :
Discharge = Mean velocity x Mean depth x Width
of Segment
of Segment
of Segment
of Segment
q(0-1) = (v1 x Bank Factor) x (d0+d1)/2 x
b0
q(1-2) = (v1 + v2)/2 x (d1+d2)/2 x b1
etc…
q(2-3) = (v2 + v3)/2 x (d2+d3)/2 x b2

(Note d0 = Depth at Water Edge)
The total discharge is obtained by adding the discharge from each segment.

Mid Section Method
(From Australian Standard AS3778.3.1
ISO 748)
The cross section is again regarded as being made up of a number of segments, however in the
mid section method each segment is bounded by the midpoint of two verticals.
The discharge of each segment is calculated as :
Discharge = Mean velocity x Depth of x Mean Width
Vertical
between Verticals
of Segment

q1 = v1 x d1 x (b0+b1)/2
