Integrated watershed study to delineate ground water prospects through Remote Sensing

Rural Development/Technology

This paper addressing the application of remote sensing and GIS technology for better understanding of the hydro geological parameters of the study area around Sagar town principally dominated by Deccan Volcanic rocks. The study carried out around Bewas Parkul sub-Watershed, covering 75.66 sq. Km. Area. This sub-watershed is the part of Dhasan basin notified as 2C2C6 in the watershed Atlas of India. IRS LISS IV Satellite imagery was used to prepare various thematic maps on scale of 1:10,000. The layers which have been integrated are in the strong co-relationship with each other, they are as follows land use and land cover, geomorphology, geology, hydro geomorphology, structure of the land form. The output layers helped in the identification of the potential zones for ground water prospect of the area. These maps can be further used in development and planning with some limitations due to seasonal variations. Lineaments and their intersections appear to be potential sites for the ground water, thus water tables level can also be estimated from this study. Thus an assessment can be done for the suitability towards construction of the surface reservoirs and the check dams which may help in the strengthening of the agricultural infrastructure over the study area. This even would be a major step towards controlling of the land degradation over the study region.
