中文摘要：
文章以桂林丫吉试验场为例,验证是否可以利用SWMM模型模拟以管道为主的岩溶峰丛洼地系统降雨径流过程。以洼地为单元,把研究区概化为由管道相连的6个次级汇水流域,选择Green-Amp入渗计算方法,同时考虑包气带裂隙水对管道的补给,运行SWMM模型计算出研究区管道总出口S31泉的流量曲线。结果显示：模拟流量变化过程与实测流量变化过程基本一致。说明该模型可以用来模拟岩溶峰丛洼地地区降雨径流过程。经验证,模拟时段内S31泉总量相对误差为19.1%。
英文摘要：
This paper presents a test study of illustrating how well the US Environmental Protection Agency＇s （EPA） Storm Water Management Model （SWMM） can simulate the flow transport in a conduit-dominated karst water system in the Yaji experimental site in Guilin. The SWMM model is a dynamic rainfall-runoff simulation model used for a single event or long-term （continuous） simulation of runoff quantity. In this study, the site was divided into 6 sub-catchments that correspond to the depressions in the catchment and the subsurface was simulated by using a dual, i.e., pore/fissure and conduit, media. The results show that simulated outflow （curve） and measured discharge （$31） of the catchment have similar variation and the relative error of total outflow in the modeling duration is 19.1%. It proved that the SWMM model can be used to simulate surface subsurface transport of flow in karst water systems in the southwest China.
