High Water content

Thermal Imaging

The technique measures the surface temperature.

Low temperatures are associated to high water

content.

Both figures presents the visible spectrum image

and the processed Infrared images.

Both images presents blue or cold temperatures

indicating the structure has high water content,

mainly in the contact between the wall and the

floor.

35

Highways, Railways & Bridges

From a geophysical perspective

36

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.

37

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.

38

Railways

Application of GPR to Railways.

Horizontal axis is distance and

vertical is depth.

All layers are parallel to the

surface and uninterrupted,

indicating a healthy section of a

given railway.

39

The layers are not always parallel

to the surface and are

interrupted. There is an important

lateral discontinuity. As resume:

an unhealth railway section.

reinforcement rebar and utilities are

detected. The arches are easily

located are pathologies, if existent,

may be determined.

layers are well visible in the type of

analysis.

Monitoring Systems

• A worldwide increasing environmental awareness and the respectivepollution control results in a constantly growing demand forenvironmental monitoring. In order to conduct time and cost effectiveas well as preventive environmental actions, detailed and profoundexpert knowledge

• Associated with reliable and sufficient data are inevitable for decisionmakers. Monitoring data are part of an essential basis for theprotection and sustainable use of natural, exhaustible and vulnerableresources such as groundwater in the future.

Monitoring Systems

The monitoring for the climatic

and hydrogeological elements is

an essential process in any

hydrogeological investigation and

Flow Monitoring

Network

• Provide reliable data for the calibration of hydraulic models or master plans

• Locate the bottlenecks of your sewer system

• know more about the diurnal variation and the peak flows

Depending on the conditions in situ we

choose the best method for the flow

measurement!

57

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

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.
