Pumping test analysis for assessment of hydraulic parameters and aquifer system formation in hilly terrain

Abstract

Abstract Groundwater conditions (GWCs) of an area depends on aquifer hydraulic parameters such as storativity () or storage coefficient (), transmissivity () and hydraulic conductivity (). It plays a key role concerning groundwater flow modeling, well performance, solute and contaminant transport assessment and also for identification of areas for additional hydrologic testing. Specifically, the geologic formation of a region controls the porosity and permeability; however, in hilly terrain prospecting ground water potential is more challenging due to its limited extent and its occurrences that are usually confined to fractures and weathered rocks. The present study aims at estimating the hydraulic parameters through pumping test analysis to assess aquifer system formation on hilly terrain from 16 bore wells. The aforesaid parameters were examined through a case study in some selective regions of Hamirpur district of Himachal Pradesh, India. The study area is controlled under two main geological horizons that is the post-tertiary and tertiary. The papers end with comparative results of hydraulic parameters and the aquifer systems formation on different GWCs, which may be helpful in the outlook of sustainable groundwater resource in the regions.
