LANDSLIDE MAPPING OF CAUVERY RIVER BASIN BY USING GEOSPATIAL TECHNIQUES

Abstract

In many region of on the earth a temporary instability of superficial mass of soil and also rocks has always been an actual natural problem. These superficial masses may leave their original positions abruptly or extremely slowly and start either a downgrade movements or vertically downward sinking thus giving rise to baffling situations in mountain region or hilly regions. These movements of the ground may entail loss to property as wel as life. Landslide may be ignored if they occur in uninhabited places and of no human interest areas but, if they occur in places of importance such as highways, railway lines, valleys, reservoirs, human inhabited areas and agricultural lands, obviously such instances lead to blocking of traffic, collapse of buildings, harm to fertile land and human life loss, so on apart from heavy loss of human life and economic properties. In order mitigate and manage the landslide disaster, need to drawn a detailed plan using available technologies and sources of GIS.
