A microprocessor-based resistivity meter for higher resolution, versatility and economy :
In geophysical prospecting for ground water, the geoelectrical (resistivity) method is often preferred for speed. economy and high resolution. It can also be used effectively in depth to bedrock studies, certain civil engineering applications, water quality studies and mineral prospecting.
The Geological Method:
The pattern of electric current flow in the ground is dependent on the sub-surface variations in conductivity. The electric potential distribution on the surface Is thus related to the sub-surface geology. The electrical resistivity of different materials being significantly different from each other, it is possible to distinguish them by their resistivity. By geological method It is possible to determine the thicknesses and depths of the different strata underneath Presence of water changes the resistivity considerably and hence can be easily located by the resistivity method. Therefore resistivity surveys are widely carried out to locate underground water resources.
In resistivity surveys electrical current is fed into the ground through two current electrodes. The resulting potential drop between two potential electrodes (generally placed between the current electrodes) is measured. Aquameter CRM generates a well regulated current (I) and measures the resulting signal voltage ay between the two potential electrodes. It then calculates the apparent resistance Ft = awi and displays it on the LCD. The effects of other ground currents and voltages is eliminated by sophisticated noise eliminating circuitry and modem electronic techniques. By multiplying R by a spacing factor which depends upon the electrode g
