Résumé
The research is to be carried out on the Girja river basin which is one of the main sub river basin of Purna river which is sub river basin of godavari. Girja River flowing through the Aurangabad and Jalna district of Maharashtra. This basin faces water scarcity problem due to erratic rainfall and change in geohydrological characters of strata which is mainly different types of basaltic flows. The water bearing characters of Alluvium aswell as Basaltic flows are different place to place. In the alluvium the different layers of clay, sandy beds play important rolein ground water occurrence. The thickness and the extent ofbasaltic flow throw the focus on availability of ground water. In Deccan Trap area the ground water occurrence mainly depends on thefactors likejointing pattern ; topographic variation, thickness and lateral extent of different flows. The study area is a part of the Deccan Plateau. In general the slopes in the district are towards south and southeast. The average elevation of the district is in the order of 500 m msl. Within it are flat topped hill ranges extending over wide area and also hills separated by broad valleys. For the investigation of the details geohydrological characters of Deccan basaltic flows Topographic Surveys, Field characters of basalt flows in Girja River Basin, Well Inventory, Geohydrological Surveys, Preparation of Geohydrological Graph, has been adapted. The studies will helpful in locating high medium and low ground water potential Zone in study area. It will also throw light on the causes responsible for water scarcity problem in study area which will help to minimize water scarcity problem of study area
