Analysis of bathymetry and spatial changes of Vembanad Lake and terrain characteristics of Vembanad Wetlands using GIS.

摘要: A number of artificial interventions, such as large-scale reclamation water bodies to form polders for rice cultivation, and unscientific construction activities have led the degradation environmental status Vembanad Wetlands Kerala State in India. Increased flood proneness is one many major issues faced region during recent decades. dynamic view spatial changes wetland knowledge on its relation various are essential scientifically planning land resources management wetlands. In this study, through development geographic data sets their analysis GIS, benchmarks established extent Lake due 20th century, bathymetry lake area—elevation—capacity relationship, topography holding capacity at different elevations.
