摘要
地面地下径流分割是水文计算、径流预报、水资源评价中一项根本性的工作。但至今仍无可靠的方法。本文在浙江高坞实验溪观测的地下径流资料基础上,从水动力学原理分析了地下径流汇流模型应采用的型式和地下径流汇流时间随流量的变化规律,提出运用产汇流联合模型法分割地面地下径流。该法经用实际资料检验与应用,表明用于山丘区流域是行之有效的,具有良好的精度。
Separation of a hydrograph into surface and groundwater runoff is a basic subject in hydrological calculation, runoff forecast and evaluation of water resources, but it is not a reliable method till now. This paper analysed the ratio nal form of a flow-concentrition model and the change law of concentritior time with the discharge of groudwater runoff based on the observed groundwater runoff data in Gauwu creek, Zhejiang and hydraulics principle, and the proposed a method of combination of runoff-contribution and flowconcentrition model to divide a hydrograph into surface and groundwater runoff. Verifying the method with many special experimental data, it is fairly effectve in mountainous-hilly basins.
