| 摘要: |
| 将水流在天然流域中的汇集过程概化为在多级河网中的汇集，从而建立了一种新的具有物理基础的过高斯分布瞬时单位线流域汇流模型。该模型不仅能用于地面净雨的汇流计算，还适用于总净雨的汇流计算。同时，在参数优选方面，提出了包括峰现时差因素在内的几种简化多目标函数，取得了明显效果。 |

| Abstract: |
| The flow concentration process in basin can be considered as the movement in multiorder river net system. Based on this rational assumption, a new kind of IUH modelInverse Gaussian distribution model has been proposed in this paper. The model input can be used not only for surface net rainfall but also for total net rainfal. At the same time, for calibrating parameters efficiently, five kinds of simplified multiple objectives including the factor of time difference of peak between measured and simulated flow have been presented also, and the good results are achieved. |
