    Abstract :

    They are important to develop effective management strategies for watersheds worldwide (Ashraf, 2013, Bazgeera et al., 2008, Caruso et al., 2005, Dietzel et al., 2005, Fortin et al., 2003, Gajbhiye and Sharma, 2012, An unplanned conversion of land under agriculture and water bodies to build up area must be checked by government legal procedures. This will enable the land to be sustained for agriculture. Kavitha.K, (2012) Remote sensing and Geographic Information Systems (GIS) are powerful tools to derive accurate and timely information on the spatial distribution of land use/land cover changes over large areas Past and present studies, mostly, has concentrated on the application of LULC changes. Tiruchchirappalli district, one of the three districts carved out of the composite district of the same name is located in the central part of Tamil Nadu between 100 18’ and 110 25’ north latitudes and 780 08’ and 790 0’ east longitudes is situated on the plains between the Shevaroy Hills to the north and the Palani Hills to the south and south-west. The city acts as an important trade centre for the surrounding districts and one of the 32 constituent administrative districts of the Tamil Nadu State. Aim and Objectives Preparation of digital geological data from Geological survey of India (GSI) for the study area. Preparation of various thematic data such Land use / Land cover Mapping using Remote Sensing Data products - IRS P6 Satellite imagery acquired during 2013 from (NRSC)Create a land use land cover map from satellite imagery using supervised classification. Find out the areas from the classified data. After having set up the objectives of the study, primary and secondary base line data .The base map of the study area has been prepared by Survey of India topographic sheets on 1: 50, 000 scales. The sequences of techniques used to fulfill the above objectives are as follows: Land use maps have been prepared using Remote Sensing Data products- - IRS P6 satellite imagery acquired during 2013 from National Remote Sensing Center (NRSC) The various Land Use / Land Cover classes interpreted in the study area include, built-up land, agricultural land (crop land, fallow land and agricultural plantation) forest (dense and degraded forest), Current fallow and other fallow occupies 30 % of the area and this implies the pressure of agricultural activities. Marungapuri, Manapparai, Mannachanallur and Vaiyampatti are dominantly found with other fallow lands followed by Thathaiyangarpettai, Musiri, Pullambadi, Manikanadam and Thiruverumpur blocks. On the district whole about 39% of the area comes under net cultivable land.
