Total Stormwater Resolution via Multiple Scale Research and Integration

城市雨水是加拿大水道中洪水和污染物的主要来源。低影响发展方案（lid）是流行的城市雨水管理技术，它模仿自然的地表水文和环境，以减少或消除污染物负荷，如总悬浮固体、营养物质、有机物、重金属、碳氢化合物（油和油脂）和有害细菌。它们还通过延长滞留时间来降低峰值流量和延迟流量。盖子可以提供零雨水对环境的影响，并有可能将雨水转化为有益的资源。然而，由于完全缺乏关于其物理功能的信息，目前的lid以一种特别的方式实现。因此，他们的表现无法预测，也无法进行计划。这种信息的缺乏部分是由于研究盖子功效所采用的方法，通常是在实验室环境中进行的，其性能评估是基于并比较盖子流出和进入的内容。这些方法并没有提供关于在LID中实际发生了什么来处理水的信息。

Urban stormwater is a major source of flood water and pollutants in Canadian waterways. Low Impact Development options (LIDs) are popular urban stormwater management technologies that mimic a natural surface hydrologically and environmentally to reduce or eliminate pollutant loads such as total suspended solids, nutrients, organic matter, heavy metals, hydrocarbons (oil and grease) and harmful bacteria. They also reduce peak flowrates and delay flow volumes by lengthening retention times. LIDs can provide zero stormwater impact to the environment and potentially turn stormwater into a beneficial resource. However, currently LIDs are implemented in an ad hoc manner due to a complete lack of information on how they physically function. Therefore, their performance cannot be predicted and planning cannot be conducted. This lack of information is partly due to the methodology employed to study the efficacy of LIDs, which is usually in a laboratory setting and performance is assessed based and comparing what goes out to what comes into the LID. These approaches do not provide information on what is actually happening in the LID to treat the water.
