As one of the subprojects in the three-year project, this study of flood inundation is mainly focused only the urbanized region along the Keelung river. The tasks of this study are to apply a numerical model, the 2D zero-inertia inundation model, and carry out inundation simulations for the Keelung river basin in the reach between Ba-Te bridge and Nan-Hu bridge. The urban inundation model is applied to simulate the inundation situations of two hundred years frequency flood wuth/without the Yuan-Shan-Tzu flood-diversion project, and the probable inundation depth and area in the study area are predicted. The inundation duration and max inundation depth are calculated to provide the useful data for flood-damage mitigation assessment and decision support system.application/pdf82838 bytesapplication/pdfzh-TW國立臺灣大學水工試驗所2D zero-inertia inundation model防洪示範區淹水境況模擬與決策支援系統之研究─子計畫:基隆河流域颱洪發生潰溢堤災害之境況模擬(Ⅲ)reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9914/1/912625Z002011.pdf
