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

城市雨水管理正面临着越来越多的挑战，由于日益严重的极端天气事件，污染的营养物质，以及新出现的关注污染物。一种解决方案是实施低影响开发绿色技术，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：生物滞留池。生物滞留单元为雨水的快速渗透提供了机会，从而防止洪水，并处理截留的径流量，从而保护水资源的质量。它们的业绩参差不齐，原因不明。** 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滞留细胞的效率和设计。** 本项目将结合联合收割机现场工作、实验室实验、工程设计和建模。该项目将与我们的工业合作伙伴和区域公共机构合作，在3年的时间内培养4名博士生，2名硕士生和3名本科生。该项目将产生新的知识，利用这些知识与私营部门和公共机构合作伙伴一起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.******
