This is a project study done by Seenivasan to know the availability of groundwater using GIS techniques.

Author: K.M.Seenivasan

This is a project study done by Seenivasan to know the availability of groundwater using GIS techniques. Groundwater lies below earth’s surface in the interstices and voids. In hard rock terrain it is mainly confined to weathered and fractured zones. In Tirunelvelli district it is being indiscriminately exploited to meet demands. Surface water storage in reservoirs and tanks are not sufficient.

This study is done for the Tamirabarani basin location.

Groundwater is our main source of water for domestic, agriculture and industrial use today and through base flows, it also maintains the flow in many of our rivers

It is therefore crucial that we look after this resource and ensure that it is managed properly.Over reliance on groundwater for both domestic and commercial purposes has led to over-exploitation and contamination of groundwater. In order to make groundwater sustainable, there is a need to understand the aquifer characteristics as well as its overall geological setting. This understanding will help in:
