Daniau Village in Daniau Creek Watershed,Taitung County,Taiwan,sustained damages from landslides and mudflows during Typhoon Morakot in 2009.The purpose of this study is to adopt the FLO2D numerical model recognized by Federal Emergency Management Agency(FEMA) to simulate the mudflow,and the Daniau Village was used as a case study,along with rainfall and digital terrain data for this simulation.On the basis of sediment yields,the residual sediment volume in the landslide area was determined to be 33,276 m 3 by comparison of digital elevation models(DEMs) and by using the universal soil loss equation(USLE).In addition,this study performed a hydrological frequency analysis of rainfall to estimate the flow discharge as conditions of the simulation.Results of disaster surveys were collected to compare with outputs of the numerical model.Results of the simulation conducted with FLO2D indicated that if the countermeasure was not destroyed,the drainage work would function without overflow.This study aimed to review the effectiveness of countermeasure on the basis of simulation results obtained by using the model to provide references for future disaster prevention and resident evacuation plans. 展开更多
