低影响开发（LID）实践减少了由于不透水表面和土地开发实践增加而产生的雨水污染和水文不稳定性。为了响应对信息和工具的日益增长的需求，以快速和轻松地评估LID实践与传统的开发实践相比，一个易于使用的基于Web的LID决策支持和筛选工具，L-THIA/LID，已经开发出来，以评估LID实践的好处。长期水文影响评估（L-THIA）Web应用程序是一个基于Web程序、地理信息系统（GIS）功能和数据库集成的决策支持系统。它为决策者提供关于土地使用变化对水的数量和质量的影响的信息。基于网络的L-THIA/LID工具建立在L-THIA能力的基础上，将使各利益相关者能够快速评估：（1）城市发展对平均年径流量的影响;（2）拟议LID做法的潜在雨水和污染物减少。拟议的土地利用变化的径流量和水质影响显示在表格，条形图和饼图。该工具的目的是使决策者能够评估和了解LID做法的影响，从而支持有效的流域规划，以实现预期的雨水管理目标。
Low Impact Development (LID) practices reduce pollution and hydrologic instability from stormwater arising from increases in impervious surfaces and land development practices. In response to increasing demands for information and tools to quickly and easily assess LID practices in comparison to conventional development practices, an easy to use web-based LID decision support and screening tool, L-THIA/LID, has been developed to evaluate the benefits of LID practices. The Long-Term Hydrologic Impact Assessment (L-THIA) web application is a decision support system based on the integration of web-based programs, geographic information system (GIS) capabilities, and databases. It provides information for decision makers on the impacts of water quantity and quality resulting from land use change. The web-based L-THIA/LID tool, which builds on L-THIA capabilities, will enable various stakeholders to quickly evaluate: (1) the impact of urban development on average annual runoff volume; and (2) the potential stormwater and pollutant reduction of proposed LID practices. Runoff quantity and water quality impacts of proposed land use change are displayed in tables, bar charts, and pie charts. The tool's aim is to enable decision makers the ability to evaluate and understand the effects of LID practices and thus support effective watershed planning to achieve desired stormwater management goals.
