We have a GPR for hydrogeological research, which is capable of measuring up to 500m in depth. The device measures linearly covering a line width of 4m and gives an accuracy of up to 95%, making it an extremely reliable and accurate device compared to the baguette survey. The method by which it measures is the so-called SP method and it is with the help of electrodes that are placed in the ground several meters from each other, with an electrical wire passing a signal from the instrument to each electrode. When a reading is taken, the instrument measures the voltage difference between the electrodes and stores the value in the computer's memory.
After that, our experienced geologists analyze the information provided by the device, namely the readings from the section and locate the places with available water saturation anomalies. The homogeneity of the environment, the water-saturated zones and the density of the earth's crust under which the study is carried out are assessed, that is, a clear idea of the earth's structure of the studied terrain is obtained. A conclusion is made at which point there should be the greatest water retention, what the intervals are and how many meters deep they are.
The tool does not give information about the quantitative state or flow rate of the water, this depends on a number of things, such as the execution of the well, what diameter it is and what submersible pump will be installed.
