本文运用流域出流断面实测地下水排入河川的地下径流量与相应的流域实测面平均地下水埋深建立地下水位与地下径流关系,通过水力因素分析,建立地下径流计算的经验模型,用来推求地下径流过程,解决平原地区地表水、地下水相互转换情况下地下径流的计算。 In this paper, the relationship between the groundwater table and the underground runoff is established by measuring the underground runoff of groundwater discharged into the river by the outflow section of the river basin and the average groundwater depth of the corresponding measured surface of the river basin. Based on the hydraulic factor analysis, an empirical model of the underground runoff calculation is established, Runoff process to solve the plain area of ​​surface water, groundwater under the conversion of underground runoff calculation.
