Abstract: 

The study aims to effects of Land Use/Land Cover Changes (LU/LCC) is the quantitative method, to expound the impact of land use/land cover changes in Ambuliyar watershed, Tamilnadu, India. The relationship between Land Use Changes and its trend is analyzed using IRS LISS III data. Further, the preparation of LU/LC map using Survey of India (SOI) Toposheet for the year of 1972 has come in handy to know the past land use pattern. Similarly, the Land Use/Land Cover (LU/LC) map of various years, namely, 2003 and 2012 which was obtained from Institute of Remote Sensing, Anna University (IRS) and digitized, is using Arc GIS 9.1 software. About 79.77 per cent of land is devoted to agricultural practices under agriculture and cropland has a major impact over the hydrological processes of the watershed. Hence, the information obtained from change detection of LU/LC aids in providing optimal solutions for the selection, planning, implementation and monitoring of development schemes to meet the increasing demands of human needs has lead to land management.
