摘要
基于垂向混合产流模型的结构特征,选择不同地区加以应用比较,率定了模型在西北干旱半干旱地区的参数,在此基础之上进行了洪水模拟计算,分析对比了模型在不同地区的应用和洪水模拟结果不合格的原因。通过分时段双源蒸散发计算和改进的格林-安普特下渗公式的应用计算,使模型在北方干旱地区和南方湿润地区也具有一定的适应性、成熟性和有效性。
The vertical-mixed runoff model was applied in different regions based on the structural feature to determine the model parameters in the northwest arid and semi-arid regions.On this basis,the flood is simulated and the reason for unsatisfactory results from flood simulation is analyzed.Through the double-source evaporation of sub-time calculation and Green-Ampt of the formula Calculation,the model also has a certain degree of adaptability,maturity and effectiveness in the northern arid and southern humid regions.
