Abstract
In this paper an attempt has been made to demarcate the land use mapping of Arjuna river basin using Remote sensing techniques. The study area is a semi-arid climatic region, which is located in the southern part of Tamil Nadu. The basin covers an area of about 1687 sq.km. The basin has been subjected to different kinds of environmental degradation by both man and nature. The analysis will help for better management for sustainable development. The analysis is based on primary, secondary and ground data. The satellite remote sensing data 1993 IRS IB LISS II and Land Sat TM were visully interpreted using the interpretation key of the NRSA (1989) classification.
The area for each of the land use categories were measured using digital plainmeter and were tabuled. The present land use / land cover pattern indicated as follow, built up land , agricultural land, forest, waste lands and water bodies.
