... nd siltation of lake, sea water intrusion, land degradation etc. The challenge therefore is, to arrest the degradational processes and restore the lake eco-system. The generation and evaluation spatial information on the terrain conditions that include Tectonic frame work, Lithology, Structure and Geomorphology of the area using geospatial technologies carried out in the present study forms an important component to address various issues in respect of land and water resources. Thus, the spatial database facilitates to formulate a scientific plan for the conservation, restoration and management of Kolleru lake ecosystem.
