GIS-based study of groundwater monitoring of villages, Karhe Region, Maharashtra, India

Abstract

This paper examines that, in the current pilot study 10 groundwater samples from 2017 to 2019 from dug wells were collected by making waypoint location of each sample by using GPS-essential receiver. The hydrological data are collected for two seasons such as dry season and wet season this study called the Double Water Table Fluctuation method. The WTF method in the dry season gives the specific yield and wet season gives the rainfall recharge. In the study area, the water table level is near about below 8m from the ground surface. The Pre-monsoon water-table level is monitored during the month March and Post-monsoon level is monitored during the month of July, etc. Groundwater presence dependence upon characteristics of terrain along with structural Geology, Geomorphology and LU/LC of the area. This study is useful for water management to local authority and farmers for irrigation purpose. The Groundwater recharge in the study area is decreased due to declines in rainfall and return flow to Groundwater from Irrigation and less pressure of surface water body. The groundwater recharge is more during the dry seasons because of more backflow from Irrigation during the Pre-monsoon seasons. The Thematic map of the study area is prepared by using Arc GIS 10.4 software.
