Beyond the black box: Developing a novel bioretention infiltration - treatment system for sustainable urban stormwater management

由于极端天气事件、营养物污染和新出现的污染物的增加，城市雨水管理面临着越来越大的挑战。解决方案之一是实施低影响发展绿色技术，以拦截、减少和处理城市雨水径流。拟议的项目将侧重于一种具有成本效益的渗透处理系统：生物保留细胞。**生物截留细胞为雨水的快速渗透提供了机会，从而防止洪水，并处理拦截的径流，从而保护水资源的质量。他们的表现是多变的，其原因尚不清楚。**该项目旨在通过详细描述控制其功能的特定水文、化学和物理过程来提高生物保留细胞的效率和设计。**该项目将结合现场工作、实验室实验、工程设计和建模。与我们的工业合作伙伴和地区公共机构合作，该项目将在3年的时间内培养4名博士，2名硕士和3名本科生。该项目将产生新的知识，与私营部门和公共机构合作伙伴一起，利用这些知识设计具有成本效益和强大的雨水处理系统。******

Urban stormwater management is facing rising challenges due to increasing extreme weather events, pollution by nutrients, and contaminants of emerging concern. One solution is to implement Low Impact Development green technologies in order to intercept, reduce, and treat urban stormwater runoff. The proposed project will focus on a type of cost-effective infiltration-treatment systems: bioretention cells.**Bioretention cells provide an opportunity for the rapid infiltration of stormwater, thus protecting against flooding, and the treatment of intercepted runoff volumes, thus protecting the quality of water resources. Their performance is variable, the reasons for which are not understood. **This project aims to improve the efficiency and design of bioretention cells through a detailed characterization of the specific hydrological, chemical, and physical processes that govern their functioning. **This project will combine field work, laboratory experiments, engineering design, and modeling. Working as a team with our industrial partners and the regional public agencies, the project will train 4 Doctoral, 2 Master's, and 3 undergraduate students over the course of 3 years. This project will produce new knowledge that will be harnessed to design cost-effective and robust stormwater treatment systems in conjunction with private sector and public agency partners.******
