摘要
本文提出了一种较为有效地考虑流域汇流非线性的方法——变速地貌单位线V^2GUH,对其特殊情况h_p=θV和i_p=K/V进行了理论证明,其动力因子流速意义得到了初步验证,坡地汇流在V^2GUH中得到了客观地考虑,应用结果证明V^2GUH方法的精度较高,同时,对本法在无资料和设计流域的应用问题进行了研究。
The V2GUH (VARIABLE VELOCITY GEOMORPHOLOGIC UNITHYDROGRAPH ) method considering well to nonlinear transit of basin is proposed in this paper. It is proved theoretically that V2GUH'S peak flow(hp) AND time to peak(tp) are specially direct and inverse Proportion to velocity respectively. The meaning of its kinetic factor is confirmed simply as the standing of velocity. The slope runoff gathering Process is really- qonsidered in the V2GUH METHOD. The application result shows that the accuracy of V2GUH method is rather higher than other methods. At the same time, the application Of V2GUH method On ungaged and design basins is studied.
