摘要: Traditional flood design methods are increasingly supplemented by risk-oriented based on comprehensive risk analysis. This analysis requires: (1) the estimation of hazard that represents intensity a flood, (2) vulnerability, e.g. percentage damage to total property as function depth and duration, (3) consequences flooding, loss life property. In this study, maps Balu-Tongikhal River system within eastern part Dhaka City prepared using geoprocessing tools hydrodynamic model. The raster-based vulnerability expected several return period floods then produced. comparison with classical inundation maps, these generate more information about flooding events. Consequently, produced useful in evaluating policy alternatives minimising because study area.
