Abstract

ABSTRACT Flood is an overflow of water that submerges land and the inflow of tide onto land. Floods usually cause large-scale loss of human life and wide spread damage to properties. In this study, integration of the satellite and GIS datasets are carried out to prepare the flood zonation mapping of Dhanera, Gujarat, India by using Arc GIS and Remote Sensing. The developed methodology processes information of seven parameters namely flow accumulation, distance from the drainage network, elevation, land use, rainfall intensity and geology. The initials of these criteria gave the name to the developed method: “FIGUSED”. The relative importance of each parameter for the occurrence and severity of flood has been connected to weight values. These values are calculated following an “Analytical Hierarchy Process”, a method originally developed for the solution of Operational Research problems. According to their weight values, information of the different parameters is superimposed, resulting to flood hazard mapping. Keywords: Flood, Risk Assessment, Dhanera, Gujarat, GIS, RS
