ABSTRACT

 

Groundwater is a treasured earth’S resource, which constitutes approximately 98.7 per cent of all liquid freshwater on the earth. It is one of our most important natural resources and is crucial to mankind. Groundwater has intricate and varied interrelations with the different component of environment and hence its intensive and imprudent exploitation results in significant environmental problems. Poor knowledge about this resource, because of it hidden nature and its occurrence in complex subsurface formation, has been and still a big obstacle to the efficient management of this important resource.

In spite of considerable improvement in our knowledge about groundwater dynamic at the dawn of the 21st century, much more still remains to be understood about groundwater in saturated as well as unsaturated subsurface formations. Advance and rapidly expanding technologies such as Remote Sensing (RS), Geographic Information System (GIS) and Global Positioning System (GPS) holds a great promise to tackle the present challenges faced by hydrologist and hydro-geologist. So in present article a review has been done about Remote Sensing (RS), Geographic Information System (GIS) application for artificial recharge of groundwater.
