摘要
研究开发了将坡面产汇流与沟、河洪水演进有机结合的水文水力学模型.模型中采用区域洪水分析、水域全区自动跟踪识别和复杂开边界过流处理等技术.模型应用于南水北调中线总干渠工程左岸牛尾河串流区洪水的仿真计算,较好地模拟了洪水期计算区域内的降雨、坡面产汇流及河沟的洪水演进、串流状况,为总干渠工程规划设计和沿线区域防洪规划提供了重要参考依据.
： A 2－D hydrology－hydraulic model of basin flood disaster is established． The water depth, velocity distribution,submerged range， duration of flood detention and so on can be obtained from the model． The model is also well applied to South to North Water Transfer Project of China,thus the position and carrying capacity of cross buildings can be reasonably arranged．
