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.
The hydrology and hydraulics model that combines the runoff and runoff generation produced by the slope and the evolution of ditches and rivers is researched and developed.The technique of regional flood analysis, automatic tracking and recognition in the whole area of the water area and overcurrent processing with complicated open boundary are used in the model.The model is applied to the midline of the South-to-North Water Diversion Project The simulation calculation of the flood in the tailrace area of the Niuweihe river on the left bank of the main canal project can well simulate the rainfall, slope runoff and river flood evolution and current situation in the flood season calculation area, Flood control planning provides an important reference.
