Title : A STUDY OF REMOTE SENSING AND GIS BASED GROUNDWATER POTENTIAL ZONE MAPPING
Bosco Biswa Kumar Debbarma

Abstract :

Groundwater is one of the most valuable natural resources, which supports human health, economic development and ecological diversity. Because of its several inherent qualities it has become an immensely important and dependable source of water supplies in all climatic regions including both urban and rural areas of developed and developing countries. Groundwater is a form of water occupying all the voids within a geological stratum. Water bearing formations of the earth’s crust act as conduits for transmission and as reservoirs for storing water. The groundwater occurrence in a geological formation and the scope for its exploitation primarily depends on the formation of porosity. High relief and steep slopes impart higher runoff, while topographical depressions increase infiltration. An area of high drainage density also increases surface runoff compared to a low drainage density area. Surface water bodies like rivers, ponds, etc., can act as recharge zones.Present study aimed various activities such as DEM map preparation, LULC map preparation, using ArcGIS 10.8 software and interpretation of the outputs. GIS and remote sensing technology is applied to prepare various thematic maps with reference to groundwater like drainage density, contour, and stream length. Slope, drainage and elevation maps were derived from the digital elevation model.
