Delineation of Groundwater Potential Zones in Vettikavala Block, South Kerala, India Using Geospatial Technology
2015
Vidhya G. S. | Binoj Kumar R. B.
Geospatial technology was utilized in this study to specifically delineate groundwater potential zones. IRS-LISS III data in conjunction with Survey of India toposheet (1:50,000) and extensive field data were used for the preparation of various thematic maps. Various thematic maps have been prepared for geology, geomorphology, slope, relative relief, land use, drainage density, lineament density, transmissivity, storativity and water table fluctuation. Thematic maps have been integrated in GIS by assigning suitable rank and weightage to each parameter based on their respective significance. Integrated groundwater potential map is a genuine tool decidedly resourceful for sustainable groundwater development and management. The charisma of this innovative method is that, this model can be used in any other area to functionally demarcate groundwater potential zones, and hence will be of immense societal significance.
