| 本文利用FLO-2D模型对台湾省东港溪流域2005年0612暴雨及2006年碧利斯台风两场降雨事件进行了淹没模拟，为保证模型参数的可靠性，将模拟结果与实际淹没调查情形进行了比较率定。依据该模型的率定结果分析了24h降雨量分别为150mm、300mm、450mm及600mm四种情况的淹没情形。结果显示降雨量为150mm及300mm时，淹没主要发生在东港溪主流沿岸区域，其他区域淹没情况并不显著；而降雨量为450mm及600mm时，淹没区域除东港溪主流沿岸外，部分低洼区域亦有较明显的淹没趋势。 |
| 英文摘要: |
| The FLO 2D program was used to simulate the inundation situations in the Tungkang River basin caused by the torrential rain on June 12, 2005 and the Bilis typhoon in 2006. In order to ensure the reliability of the simulated results, the model parameters were verified and calibrated by comparison with in situ investigation results. On this basis, the possible inundation of four rainfall scenarios, included 150mm/d, 300mm/d, 450mm/d and 600mm/d, were simulated by using the calibrated model. The results indicate that the submergence mainly occurs to the coastal region of the Tungkang Creek, the inundation of other regions are not severe as the rainfall varies from 150mm/d to 300mm/d, and the inundation will occur to the other low lying area besides the coastal region of the Tungkang Creek as the rainfall varies from 450mm/d to 600mm/d. |
