摘要
Abstract
Due to large watershed area and lack of hydrological stations on the middle and upper reaches of the Yarlung Zangbo River, flood forecasting can’t be carried out effectively. Based on DEM, the paper uses hydrological analysis function of ArcGIS and makes watershed segmentation in this region. By generating drainage lines, dividing watershed sub-units and generating the topology relation between partitions, the distributed flood forecasting scheme is established. According to the watershed characteristics on the middle and upper reaches of the Yarlung Zangbo River, Xin’anjiang Model and Muskingum flood routing Model are applied to simulate hydrological process of the watershed. The results show that the forecasting scheme can better simulate hydrologic process of important stations.关键词
