Natural Coastal Processes And Its Geo-Environmental Impact In The Area Between Chennai And Nagapattinam Coast Of Tamilnadu And Pondicherry
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 8
Abstract
Natural coastal /marine processes affect the coastal areas making significant changes in the morphology and associated ecosystem. Geo-environmental appraisal of Tamil Nadu coast between Chennai in the north and Nagapattinam in the south was made by identifying the areas of impact due to ongoing dynamic changes along the coast. The various thematic data such as geological, geomorphological, landuse, ground water etc. was synthesized and field verified to arrive at regional impact assessment for the study area. Apart from sea erosion and progradation, other geological processes taking place in the study area include submergence, silting of lagoons, and growth of spits across tidal inlets and rivers, flooding, high wind, increased salinity/ iron content in soil and water. The information gathered can be an input in the formulation of remedial measures and effective utilization of coastal area resources.
