Flood damage and management modelling using satellite remote sensing data with GIS: Case study of Bangladesh

Abstract

Physiographic divisions, geological divisions, land cover categories and drainage network data were used as GIS components. Flood frequency and floodwater depth were estimated using NOAA AVHRR data for the development of a flood hazard map. The flood hazard map provides information for the development of counter measures and preparation of high risk areas, on a priority basis, against flood damage. It is concluded that the flood hazard map, which was developed by considering the interaction of floodwater depth and flood frequency, gives good results for other events.
