Resistivity Well Logging to Delineate Lithology in Hard Rock. Resistivity well Logging Hard Rock Terrain

      Аннотация: Water is the most vital element for the life. Most of the rural population in India does not get good quality of water even for drinking. A number of factors contribute to the scarcity and pollution of the water. While the wide spacio-temporal variations of rainfall and hydro geological conditions are the main reasons for the scarcities, illiteracy, lack of education and industrial effluents are the other reasons for pollution of water. Therefore, it is necessary to utilize proper scientific management methods for optimal utilization of water resources. This investigation was carried out as a part of the systematic study to understand the subsurface lithology for groundwater management.In the present study area Groundwater is the only source for domestic and agricultural needs. There is no surface water supply for both usages. The study area completely falls in the complex crystalline granite rocks. Therefore, delineation of aquifer zones and finding of subsurface lithology by using geophysical well logging survey is a challenging task. Gajwel watershed has been chosen for detail study of hard rock hydrogeology by using geophysical methods
