摘要
流域汇流可以概化为洪水波的平移和坦化作用 ,平移和坦化模拟是大多数概念性汇流模型的核心。该文通过 13个特小流域的汇流模拟计算 ,研究了特小流域的汇流特征。模拟结果发现 ,特小流域汇流的平移作用不明显 ,流域调蓄作用主要是坦化作用 ,汇流模型主要是坦化作用的模拟。同时由于特小流域集水面积小 ,流域调蓄能力小 ,用于模拟坦化作用的水库数量参数也比大、中。
Runoff concentration can be generalized as transposition and attenuation of flood waves, which are the basis of most basin runoff concentration models. This paper focuses on mini basin characteristics of runoff concentration based on the simulation and computation of 13 mini basins. The transposition effect is very small and the attenuation effect is the main of storage effect in mini basins. So mini basin runoff concentration models should focus on the simulation of attenuation effect. Further more, the number of simulate reservoirs is fewer than that of large, medium and small basins.
