| Summary: | 碩士 === 淡江大學 === 水資源及環境工程學系碩士班 === 98 === This study investigated the theoretical background and the requirement parameter of the Hydrologic Modeling System (HEC-HMS), which developed by U.S. Army Corps of Engineering Center, and applied HEC-HMS to simulate five typhoon events on the upstream of Xindian River basin in Taiwan. First, combined ArcGIS and HEC-HMS, namely used ArcView as a service platform, then picked up the
physiographic factors by using ArcHydro tool and HEC-GeoHMS, achieved HEC-HMS input file and hydrologic elements setting automatically.In HEC-HMS, a project was created which contained separate models: Basin Model 、Meteorologic Model and Control Specifications. That may specified
different data set for each model and then the hydrologic simulation was completed by using of data set for those three models. Study area was divided into five subbasin,
and Meteorologic Model used “User Gage Weighting Method” ; In Basin Model,Loss Method used” Initial and Constant Rate”, Transform Method used” Snyder’s
Unit Hydrograph”, Baseflow Method used” Recession”, and River Routing used”Kinematic wave”. Estimated the values of the parameters, according to the discharge
hydrograph of five selected typhoon events, the hydrologic parameter characteristics of the basin could be modifed by try and error, finally choosed the least error and discussed.
