Aquifer Response at the Proximity of Patalganga and Shriganwadi Micro-Watersheds, Nanded District, Maharashtra Using Groundwater Flow Model

Abstract

Groundwater modeling is necessary to get correct information of aquifer response for management of groundwater resources. In this paper, we have simulated groundwater flow of two micro-watersheds (namely Patalganga and Shriganwadi) located Nanded, Maharashtra considering the field data such as aquifer properties, recharge, discharge, and other required information obtained from literature using Visual Modflow ver. 3.1.0 for the year 2021. Then the model compared with the observed groundwater level at the selected wells, which are reasonably matched in the field data. It was also simulated by changing a few dominant input parameters in a limited range. After the validation of the model, it was run for the different environmental stress scenarios, which can occur in future. The model reactions of the aquifer response had been checked and it has observed drying a few well sites in these micro-watersheds. It will help to the decision makers for sustainable management of groundwater resources.
