Continuous urbanization has negatively impacted the ecological and hydrological environments at the global, regional, and local scales. This issue was addressed by developing Low Impact Development (LID) practices to deliver better hydrologic function and improve the environmental, economic, social and cultural outcomes. This study developed a modeling software to simulate and optimize bioretentions among LID in a given watershed. The model calculated a detailed soil infiltration process in bioretention with hydrological conditions (e.g. unsaturated and saturated soil) and hydraulic facilities (e.g. riser and underdrain) and also generated an optimized plan using Flow Duration Curve (FDC). The optimization result from the simulation demonstrated that the location and size of bioretention, as well as the soil texture, are important elements for an efficient bioretention. We hope that this developed software will aid in establishing effective LID strategies for improving urban water sustainability and management.

持续的城市化对全球，区域和地方范围的生态和水文环境产生了负面影响。通过开发低影响开发（LID）实践来解决此问题，以提供更好的水文功能并改善环境，经济，社会和文化成果。这项研究开发了一种建模软件，用于模拟和优化给定流域中LID之间的生物保留。该模型计算了在具有水文条件（例如，非饱和和饱和土壤）和水力设施（例如，立管和暗渠）的生物保留条件下的详细土壤入渗过程，并使用流量持续时间曲线（FDC）生成了优化计划。仿真的优化结果表明，生物保留的位置和大小以及土壤质地，是有效生物保留的重要元素。我们希望该开发的软件将有助于建立有效的LID策略，以改善城市水的可持续性和管理。
