摘要
根据概念性流域地貌汇流模型的一般理论,以概念性元素"线性动力波河段"模拟各级河道的汇流作用,建立了基于线性动力波的地貌瞬时单位线模型.给出了三级流域瞬时单位线的表达式,并分析了模型参数对瞬时单位线的影响.讨论了参数的约束条件和参数的推求方法,并对南雁流域的雨洪资料进行了实例分析.
According to a general theory of conceptual watershed geomorphic concentration model, using the conceptual element of linear dynamic wave reach to simulate the concentration action of each ordering_unit channel, a geomorphic instantaneous unit hydrograph model is developed based on linear dynamic wave. The instantaneous unit hydrograph of three_order basin is derived; and the effect of the model parameters on the instantaneous unit hydrograph is analyzed. The constraint conditions of the parameters and the method for solving the parameters are discussed. An example about Nanyan basin is attached.
