摘要
正确估计地下径流过程是水文计算和预报中的一项基础性工作。本文结合高坞溪实验区的地面、地下径流观测资料和流域降水,从水力学原理上分析了地下径流计算的模型结构和地下汇流时间随流量变化的规律,从而建立了一套产汇流模型相结合的地下径流计算方法。经用专门的实验资料检验,证明该法用于山丘区有森林覆盖的流域是行之有效的和成功的。
How to compute groundwater runoff correctly is the basic re- search subject in hydrological calculation.It analysed the experimental data of groundwater runoff in Gauwu Creek and the law of effect of discharge on collecting time,proposes a method of combination of runoff yield and collecting to compute groundwater runoff based on hydraulics principle. It is found that the method is fairly effective in mountainous-hilly coun- try with forest through testing with lot of special experimental data.
