Identification of geomorphological and geological features in between valinokkam and Thoothukudi coast using remote sensing and gis technology

An attempt is made to study the mapping of geomorphologic features, using remote sensing and GIS techniques in the coastal Valinokkam to Thoothukudi. The geology and geomorphological characteristic's world coastline are significant for safe guarding natural disaster management and to improve of our economic conditions. Those observations on coastal research have been motivated over the past hundred years. Geology and Geomorphology are an essential part of our coast, and for every coastal person in this country. An effort is made to study the geologic and geomorphologic characteristic features from Valinokkam to Thoothukudi in the east coast of India. The geologic characteristic's features are carried out from GSI map (1:50000 Scale) maps prepared under six different types of rocks as laterite formation (Czl), marine sediments (Qm), fluvio marine (Qfm), fluvial (Qf), sand stone with clay (N1cs), and Hornblende biotite gneiss (Amh). Naturally geomorphology of the study area is self-possessed by Gondwana formation, which is exposed at Thoothukudi and Ramanathapuram districts. The satellite image's IRS P6, LISS III utilized to trace out the different geomorphological features like saltpan, backwater, sand dune complex, beach ridge, tank, settlement, harbour, swale, back water, pedi plain, alluvial fan.
