CWRDM has undertaken studies for locating potential groun<twater
zones in Greater Chaliyar basin through remote sensing. The objective of this study
was to map the hydrological, morphological and geological aspects of Greater
Chaliyar basin which includes the sub-basins of Kadalundi, Chaliyar, Kallai and
Korapuzha. The study was carried out in collaboration with Indian Institute of
Remote Sensing (IIRS), Dehradun. The landsat imagery, aerial photographs and
toposheets have been made use of to prepare detailed maps showing ]jneaments, ela
distribution, drainage density, and other geomorphological features. This
study has revealed that most ot the elas are fracture controlled
and promise good recharge and discharge sites. The prominent lineament
direction has been found to be NE-SW. The study of prominent
hydrogeomorphological features has indicated that Kadalundi subbasin is the
most promising for groundwater exploration.
