Environmental Impact Assessment of Thamirabarani River Basin, Tamil Nadu using Remote Sensing and GIS Techniques


Objective: To assess the landuse and landcover along with rainfall, to monitor the changes in waste and degraded lands, and to assess the water quality parameters mainly on TDS and Chloride and its impact in environ and to take the necessary action. Methods/Statistical Analysis: Land use/Land cover map, geology, geomorphology, drainage and waste lands maps were prepared using IRS P6 satellite Imagery. Rainfall details of 30 years were collected in the meteorological department and water quality samples were collected in control wells for pre monsoon and post monsoon season and using interpolation technique and overlay analysis, assessed the water quality and landcover changes. Findings: Using this analysis, the study clearly indicates that wasteland extent is increasing year by year due to the various water quality and rainfall changes. Micro level planning of water source and quality will increase the good environment. And identified the favorable sited for augment ground and surface waters bodies. Applications/Improvements: Suggestion to convert the wasteland into productive lands and sustainable developmental activity like construction of check dams, rehabilitation of tanks & canals, rainwater harvesting structures, and waste water recycling.
