Identification of groundwater potential zones, depth to water level and water level trend in Deori Tehsil, Central India: using geospatial techniques

Abstract

The geospatial techniques are being used in this research to determine the depths, trends, water levels, and likely groundwater zones in the Deori Tehsil. In the research area, topography maps of India and water quality analysis are used to define physical parameters for the inverse distance weighting (IDW) interpolation method. The soil slopes from 150 to 300 m at this point. With the branches of Navegaon Mountain and Chichgarh Hills to the south of it, it is situated 302 m above sea level. The study shows that the pre-monsoon water levels in the deeper aquifer range from 5.7 to 14.85 mbgl in May 2021, and the post-monsoon water levels in the deeper aquifer range from 0.2 to 2.5 mbgl in November 2021. This study region has the highest drinkable water quality (41.27%), followed by excellent water (17.46%) and good water (23.81%). This is because there is not much urbanization in the area, the water quality is excellent, and there is developed agricultural land nearby. There, the quality of the water appears to have declined. It has a capacity of 30.16% for bad water, 7.94% for unsuitable water, and 20.63% for extremely poor water, all of which are good for drinking and farming.
