Assessment of Land use Land Cover Changes in Ennore River Mouth of Thiruvallur District, Tamil Nadu, South India

Coastal zones are the most vulnerable area for land use changes due to its rapid development of urbanization. Evolution of land use land cover along the coastal estuary has got importance because of drastic development. The main objective of this paper is to evaluate and quantify the land use /land cover and its changes of Thiruvallur estuary from 2004 to 2016 using multi – temporal satellite images and digital change detection techniques. The changes were carried out using ERDAS image processing and ArcGIS softwares. The study proves it’s significant on changes of land use /land cover in the river mouth area. The comparison of land use/land cover for the period of 2004 and 2016 derived from satellite imagery interpretation indicates that there is a significant increase in built – up land area, water body, and vegetation lands.It noted that substantial amount of scrub land and wetland area vanished during the period of the study which due to rapid urbanization of the area.
