三参数变动单位线

Three-Parameter Variable Unit Hydrograph

为了处理流域汇流和河道洪流演进中的非线性问题,本文用非线性马斯京根(Muskingum)蓄泄关系与水量平衡方程联解,推导出三参数变动单位线,并分析了模型参数的特性,探讨了以马斯京根蓄泄关系和水量平衡方程为基础的三参数变动单位线模型具有的滞时性。

The non-linear Muskingum storage-discharge relation and continuity equation are used to treat with the drainage-basin concentration or the channel flood routing. A three-parameter variable unit hydrograph is developed, and the parameter properties are analyzed. It is also studied that the three-parameter variable unit hydrograph model based on the Muskingnm storage-discharge relation and the continuity equation is a lag-time one.
