Summary

The study focused on the preparation of Triangulated Irregular Network (TIN) from available cross section data, contours and spot elevations, calculation of water surface profiles by steady and unsteady flow analysis, delineation of the flood areas, risk mapping, and creation of flood animation. The approach adopted for the study consisted of dividing the risk into vulnerability associated with land use pattern and hazard associated with hydrological and hydraulic parameters. The results of these analyses were combined to see relationships such as discharge-flood area and flood depth-land use. A series of maps were prepared depicting different relationships, such as discharge-flood area and flood depth-land use.
