Highways
Application of GPR to Highways.
Horizontal axis is distance and
vertical is depth.
All layers are parallel to the surface
and uninterrupted, indicating a
healthy section of a given highway.

In this case, the layer is not continuous,
and it disappears in the middle. This is
due to the fine materials produces due
to deterioration.
The layers are not always parallel to the
surface and are interrupted, indicating
unhealth sections of a given highway.

Flow Monitoring
Infiltration
Depending of the structure of the system measurements willeither be carried out:
• in gravity lines for the determination of infiltration ratesfrom the daily flow minimum
• at pumping stations that collect the water of an area
• Calculation of the pumped volume with simple level
measurement
• No affection of normal operation
• Measurement of only 3 days leads to essential information

Pumping Stations
• Depending on the measuring task and the type of pumping station TDS provide:
• Discharge measurement, calibration and runtime statistic for each pump
• Evaluation and presentation of the acquired data

Benefits:
• know the real capacity of your pumping stations
• Get more information about the peak flow
• Detect where is the bottleneck , Is it the network or the pumping station?
• Confirm whether the frequency of pump-starts comply with the
requirement not to start more than 10 to 15 times/h?

During the life of a well periodical well rehabilitation is needed.
Causes of decline in well performance, declining of the well
yield, are mechanical, chemical and biological. Each cause
requires different approach and before any attempt is tried to do
well rehabilitation thorough examination of well is needed.
Based on your data, such as:
• camera inspection of well
• construction details of well
• history of pump tests
• chemical analysis of water from well
• analysis of Iron Bacteria, Sulphate Reducing bacteria and Slyme
bacteria
• mineralogical analysis of incrustation
We can determine exact procedure for well rehabilitation.

� Flood study
� Flood study and modelling
Flood modelling allows estimating a full range of
possible flood severities (+1000 years) at each location. The output
is the derive the annualized cost of flooding at an individual location
level.
Our services:
•Flood frequency analysis ( calculation , software)
• Rainfall-runoff modelling
• 1D, 2D, and 3D floodplain modelling
• GIS-based flood damage and evacuation capability assessments
• Flood risk and emergency response mapping
� study and dimensioning of rainwater drainage structures
