The present work accentuated the expediency of remote sensing and geographic information system (GIS) applications in groundwater studies, especially in the identification of groundwater potential zones in Ithikkara River Basin (IRB), Kerala, India.

The mechanised sand mining by employing workers from other states is posing danger to the environment and the bridges across the river at Ithikkara, Kummallur and Kundumon.
