Hydrogeological study of parts of Mahesana district using Remote Sensing and Geographical Information System (GIS)

Abstract

A systematic hydrogeological study has been carried out to study the nature of ground water conditions of the Mahesana districts. In the study a combined approach of remote sensing and field survey have been carried out to obtained information about the different lithology, geology, geomorphology and structural units contained in the study region having potentiality of water storage and discharge. In this study, Satellite images of LANDSAT supporting with field data is used to demarcate the hydrogeological formations, land-use, land-cover pattern and lithological units which are encouraging the potentiality of groundwater in the study area. Survey of India (SOI) toposheet, No: 46 A/6 have also been used, for the preparation of base map of the study area. Geo-reference processing, classification of satellite data and preparation of different maps has being carried out with the help of ArcGIS and ERDAS imagine processing software. Additionally pre and post monsoon water level depth data has been taken during field survey in order to calculate the seasonal groundwater fluctuation in the study area.
