Abstract

Due to rapid industrialization and increase in human population, there has been a tremendous pressure on the water resources. In hardrock terrain, the availability of groundwater is confined to fracture and weathered zones. In the present study, the study area is Dhanbad district of which most of the parts lie on hardrock terrain. In this study, an attempt has been made to relate the fluctuation of groundwater level with hydrogeological factors. The various hydrogeological factors that have been considered here which can affect the aquifer recharge are geomorphology, geological structures, geological formations, soil types, and elevation. These hydrogeological factors have been analyzed for 65 monitoring wells and frequency plots between different hydrogeological parameter classes, and water level fluctuation have been used to assess the relative impact of different hydrogeological subclasses on aquifer recharge. Further statistical analysis has been done for all hydrogeological parameters for each subclass based on mean, median, mode, and standard deviation values to further specify the relative effect of each subclass within different hydrogeological parameter. Based on the findings, it has been concluded that there is a definite relationship of surface topography, geology, geomorphology, soil, and elevation with recharge of aquifers based on their specific hydrogeological properties.
