SUB-BASIN DELINEATION METHODS FOR SWAT MODEL IN PLAIN RIVER NETWORK REGION
摘要
Abstract
Sub-basin SWAT model applications in plain river networks face at least three difficulties. One difficulty is that sub-basins and rivers from DEM data do not agree well with practical situations. The divarieated or braided stream can not be identified by SWAT model. One further difficulty is that water-control projects affect seriously flow routing processes. Possible corresponding solutions were proposed. DEM could be corrected by modifying manually the elevation value and flow direction. Divaricated streams could be treated as trans-sub-basin water diversions, and river networks could be generalized rationally. Alternatively, sub-basin boundaries could be drawn manually and virtual reservoirs could be added. Watershed delineation results using these methods agreed well with the realistic hydrologic processes in plain river network region and would meet the demands of subsequent model setups and applications.关键词
