主　　题：Flood forecasting Liuxihe model Urbanization Pinang watershed 

摘      要：Urbanization has been a worldwide development trend,which regulates river courses,impervious surfaces and drainage *** causes hydrological effects,including increased runoff volumes,peak discharges and flow *** manuscript selects the Malaysian Sungai Pinang watershed as a case study to illustrate these land use,channel and flooding changes of Asian coastal *** Landsat satellite remote sensing images were first used to estimate the land use/land cover changes of the Sungai Pinang watershed by using SVM algorithm,and the results shows the urbanization was very rapid in the past decades,with the urbanization rate reached 46.41%in 2018 based on the build area *** channel characteristics also changed significantly,from natural river to concrete *** flood resilience measures for coastal cities experiencing urbanization are also proposed for development and flood ***,a flood forecasting model of the Sungai Pinang watershed is established *** simulation results of the Liuxihe model constructed in this study conforms to hydrological regularities and can provide a technical reference for flood control and disaster ***,it is necessary to pay attention to the uncertainty of the forecast results.
