Flood Risk Mapping for Different Landuse Senarios Based on RS and GIS
Beginning from the study on influencing mechanism of urbanization on flood risk, various influencing indicators of flood risk in urbanized areas are researched, presenting that the change of land use, lagged underground drainage, urban heat island effect, accumulative population, wealth and public infrastructure which make cities——the hazard bearing bodies more vulnerable and flood risk increase as well. Supported by RS and GIS, taking Changzhou as an example, the indicators of urbanization shown by two landuse type maps extracted from TM in 2001 and 2008 on flood risk are analyzed together with DEM and distance to discharge channel, it found that urbanized degree and flood risk are a positive correlation, flood risk in more highly urbanized areas is greater, as a consequence of vulnerability and exposure of urban areas increasing.
