Groundwater Potential Modelling and Aquifer Zonation of a Typical Basement Complex Terrain: A Case Study

Abstract Geophysical exploration using Vertical Electrical Resistivity (VES) techniques has been employed to study the groundwater potential and vulnerability of selected locations. The objective is to investigate nature and groundwater yielding potential of the area under investigation and to understand roles of various geophysical parameters in groundwater potential of the area and their effective characterisation of hydrogeological units. The juxtaposition of contour maps which show variations in hydrogeological parameters in a continuum manner is worthwhile. The results have really shown that the general trend of groundwater potential within the study area is low as indicated from the hydraulic conductivity, transmissivity and porosity. The generated groundwater potential map of the area can be used in designing appropriate groundwater exploration and management within the area and can serve as a roadmap for further expansion of the research work.
