Abstract

Lineaments are potential zones for the occurence and movements of groundwater. Delineation of lineaments from the satellite imagery interpretations are normally confirmed by earring out adeqate field checks, well inventory and geoelectric surveys. Surface geophysical methods are used in conjuction with the lineament maps to identify the suitability of specific sites for groundwater development. Tambraparni River basin, situated in the southem part of Tamilnadu, is a typical crystalline terrain, where the occurence of groundwater is controlled mainly by the geology and structural features including lineaments. This study aims to correlate the hydrogeological condition of the area with the satellite imagery interpretation and geoelectric field observations. Interpretation of satellite data have shown that the flow of Tambraparni River and its tributaries, including Chittar, are controlled by the presence of major lineaments. Analysis of longterm waterlevel data revealed that the river Chittar is an effluent Stream and the position of the major groundwater flowlines were found to be away from the river which is a unique feature in a groundwater system. It is also seen from the longterm records that the river discharge seems to be very low.
