Abstract:

The article discusses issues related to the development, research and testing of a new method of mathematical modeling and field testing of geoecological monitoring systems based on geoelectric methods of geodynamic control. The method being developed involves creating the effect of the presence of near-surface and deep-seated inhomogeneities using additional point or extended sources (electrodes of various shapes, cable sections of various lengths and shapes, etc.). The problem with the known methods of physical (full-scale) modeling of geoelectric sections is the rigid specification of the g

Abstract Recently, Upper Metro Sub-Catchment and its surroundings have witnessed intensive land investments.

Therefore, in order to better define the catchment area and find new sites that meet the water quality and quantity requirements, a geoelectrical survey using

Electrical resistivity method was used to carry out hydrogeophysical study in order to evaluate the groundwater potential of Igarra Comprehensive High School, Akoko Edo Local Government, Nigeria. The vertical electrical sounding technique (VES) was adopted for the resistivity method. A total of eighteen electrical soundings were conducted across the area using the Schlumberger electrode array with AB/2 varying from 1 to 65 m. After the data acquisition, interpretation was carried out qualitatively and quantitatively and the results were presented as sounding curves, tables, charts, maps and ge

Abstract:

A hard rock area underlain by granitic/gneissic or basaltic rocks often has an A‐type three‐layer geoelectric section in which resistivity increases with depth. The middle layer of moderate resistivity caused by fracturing/fissuring that lies between the surface‐weathered layer and the substratum of unfractured rock is not a good target for a direct current (DC) resistivity sounding since it is generally suppressed in the observations. Moreover, its definition requires expanding the electrode spacing to a length several times the depth of the target layer, and this may be a drawback if the tar

Interpretation of vertical electrical soundings (VES) and study of lithologic logs were carried out to identify the geoelectric/hydrogeologic characteristics of the Basement Complex rocks in the area south of Zakum Bello. Geoelectric sections drawn from the interpretation results (layer resistivities and thicknesses) reveal mainly four to five layers with the first four layers constituting the weathered basement. Two aquifer types were identified. These are fractured (confined) and weathered (unconfined) aquifer. Ground water yield varies from 0.63 L/S (for the weathered layer aquifer) to 0.28
