FLOOD INUNDATION MAPPING USING SPATIAL TECHNIQUESline

S. G. Sarkar , D. R. Vaidya

This paper discusses the role of various spatial techniques available for extracting the flood inundation map for river basins. Flood inundation mapping is a vital component for appropriate land use planning in flood-prone areas. In this paper examples of some previous case studies are included to illustrate how spatial techniques are being used now days for preparing flood hazard mapping. Flood inundation mapping is a basic tool for flood preparedness, mitigation activities and also flood insurance programs. For flood management it is always necessary to monitor continuously as floods are among the most recurring and devastating natural hazards, impacting human and causing severe economic damages around the globe. The current trend and future scenarios demand accurate spatial and temporal information on the potential hazard and risks of floods. Today, spatial techniques especially remote sensing, geographic information system (GIS), digital elevation model (DEM) have become practical tools for development of cost effective methods for flood inundation mapping in gauged and ungauged river basins.
