The goal of this research is to test the hypothesis that stormwater Best Management Practices (BMPs) positively influence ecosystem function of urban streams at multiple spatial and temporal scales. This project will assemble a comprehensive set of measures to determine the impact of BMPs on water quality in several urban watersheds. Interdisciplinary aspects include water quality analyses, stream morphology, and ecological monitoring and modeling. Placement, design, and density of BMPs will be investigated to determine the optimal benefit for stream ecosystem services, such as nutrient uptake, metabolism, temperature and biological indices. The results of monitoring BMPs will be combined with ecological modeling of nutrient concentrations to identify the areas best served by BMPs and how well the BMPs function to achieve the over-arching goal of improved stream health. Inclusion of thermal pollution is an important component of this research. Undergraduate students will be heavily involved, and will gain experience in design of environmentally friendly BMPs. The involvement of a stakeholder group will transfer the results to people who can use the results to influence current stormwater regulation and management practices.Bruce K. Hamilton7/6/10

本研究的目的是测试的假设，雨水最佳管理措施（BMPs）积极影响城市河流生态系统功能在多个空间和时间尺度。 该项目将汇集一套全面的措施，以确定最佳管理计划对几个城市流域水质的影响。 跨学科方面包括水质分析，河流形态，生态监测和建模。BMP的放置，设计和密度将被调查，以确定流生态系统服务的最佳效益，如营养吸收，代谢，温度和生物指标。 监测BMPs的结果将与营养物浓度的生态模型相结合，以确定BMPs最适合的区域，以及BMPs的功能如何实现改善河流健康的超临界目标。 包括热污染是这项研究的一个重要组成部分。 本科生将积极参与，并将获得设计环保BMP的经验。 利益相关者团体的参与将把结果传递给那些可以使用结果来影响当前雨水调节和管理实践的人。汉密尔顿7/6/10
