Flood damage monitoring for the low-level plain in Vietnam by Remote Sensing

摘要

A lumped model for inundation was constructed for the flood that occurred in the east Vamco basin of the suburb of Ho Chi Minh City, Vietnam, in October 2000. A time series of change in the inundation area was simulated. The storage function method was used as a lumped model. Nearby rainfall data were used as an input, and the runoff was calculated with the sea level variation. Next, the storage depth was converted to the flood depth with Shuttle DEM, and yielded a time series of inundation area with GIS. This result explained the flooding state from satellite data very well. Flood simulation was constructed by satellite observation and a flood analysis with the storage function method. This method would be available for flood forecast.
