Geomatics and geohazards of Tamil Nadu coast India

The geohazards have become fast-spreading epidemics all over the world. Especially the coastal zones are more susceptible to various disasters due to the interplay of tectonics riverine coastal and aeolian processes. The authors using various geomatics tools (remote sensing image processing analysis of SRTM data DEM based visualization GIS modelling and so on) analyzed the tectonic fluvial and denudational geomorphic anomalies. Amalgamating them developed a comprehensive morphotectonic and morphodynamical model for the Tamil Nadu coast India. From there authors studied the seismic tsunami flood and other environmental hazards and eventually figured out plausible mitigation strategies.
