The purposes of this study are to propose the new approach for modeling the effectiveness of low impact development (LID) practices using Hydrological Simulation Program-Fortran (HSPF)'s Surface-FTABLE (function table) and to evaluate the impacts of LID application on hydrological components and water balance. LID was simulated using Surface-FTABLE, and changes in hydrological components and water balance were analyzed. These results were compared with results simulating LID using the HSPF LID Controls Tool built in the HSPF model. Embedded within the HSPF model, the HSPF LID Controls Tool is used to design and simulate infiltration-based best management practices. Surface runoff decreased similarly for both methods using Surface-FTABLE and LID Controls Tool. For Surface-FTABLE, the infiltration in the facility was reflected in the model, so interflow, outflow and baseflow outflow increased. As a result of the water balance analysis, the results of Surface-FTABLE showed a similar bias to those of the model without LID. In contrast, the results of the LID Controls Tool showed a large bias due to uninvolved infiltration. This study showed that HSPF Surface-FTABLE is applicable to LID simulation and that it is possible to simulate the change of each element of hydrologic components reasonably.

本研究的目的是提出使用水文模拟程序-Fortran (HSPF) 的 Surface-FTABLE（函数表）对低影响开发 (LID) 实践的有效性进行建模的新方法，并评估 LID 应用对水文成分和水平衡。使用 Surface-FTABLE 模拟 LID，并分析水文成分和水平衡的变化。这些结果与使用 HSPF 模型中内置的 HSPF LID 控制工具模拟 LID 的结果进行了比较。嵌入在 HSPF 模型中的 HSPF LID 控制工具用于设计和模拟基于渗透的最佳管理实践。对于使用 Surface-FTABLE 和 LID Controls Tool 的两种方法，地表径流的减少相似。对于 Surface-FTABLE，设施中的渗透反映在模型中，所以流入，流出和基流流出增加。作为水平衡分析的结果，Surface-FTABLE 的结果显示出与没有 LID 的模型类似的偏差。相比之下，LID 控制工具的结果由于未受累的渗透而显示出很大的偏差。研究表明HSPF Surface-FTABLE适用于LID模拟，可以合理地模拟水文分量各要素的变化。
