Multi-criteria Decision Making and Geo-spatial Technology in Groundwater Studies

Groundwater is a dynamic and replenishing natural resource. But in hard rock terrains, availability of groundwater is of limited extent. Occurrence of groundwater in such rock is essentially confined to fractured and weathered horizons. Poor knowledge about this resource, because of its hidden in nature and its occurrence in complex subsurface formations, has been and is still a big obstacle to the efficient management of this important resource. The present study aims in the identification and delineation of groundwater potential zones by combining remote sensing, geoinformatics and multi-criteria decision making tool (AHP analysis) techniques in Korapuzha river basin which falls in Kozhikode districts of Northern Kerala, India.
