Abstract: | The Deccan Volcanic Province (DVP) of India, as a whole, faces a severe shortage of water despite receiving a high annual
rainfall, this is primarily due to excess runoff and lack of water conservation practices. In this study, an attempt is made
to identify zones favourable for the application and adaptation of site-specific artificial-recharge techniques for augmentation
of groundwater through a Geographical Information System (GIS) based hydrogeomorphic approach in the Bhatsa and Kalu river
basins of Thane district, in western DVP. The criteria adopted for the GIS analysis were based on the hydrogeomorphological
characteristics of both basins extracted from the IRS-1C LISS-III data supported by information on drainage pattern, DEM derived
slope, lineament density, drainage density, and groundwater condition. The integrated study helps design a suitable groundwater
management plan for a basaltic terrain. |
