Monitoring Evaluation Vegetated Stormwater Infrastructure

项目摘要

Flood risk is a significant threat to many residents of urban areas. Vegetated stormwater infrastructure (Sustainable Drainage Systems or SuDS) can provide stormwater management that is resilient to future climate and land use changes. However, quantitative evidence confirming the hydraulic performance of SuDS in practice is limited. Such evidence is urgently needed to inform Government policy making and water industry investment, and to support the development and validation of modelling tools used to plan and design drainage infrastructure. Severn Trent Water's ambitious programme for town wide SuDS retrofitting in Mansfield provides a unique opportunity to collect key evidence on how these systems perform in practice. The project will primarily utilise field data (in-sewer/SuDS flow and void space level data) that is already planned to be collected by Severn Trent Water. In addition, we will intensively instrument at least one individual device (e.g., a bioretention cell, or 'rain garden') to permit detailed data collection and scrutiny of the modelling tools, with the goal to recommend improvements to SuDS modelling and design. In addition to natural rainfall events, we will engineer artificial rainfall/inflow inputs into this device to provide test-case data corresponding to extreme design rainfall events.

洪水风险是对许多城市居民的重大威胁。植被雨水基础设施(可持续排水系统或SODS)可以提供对未来气候和土地利用变化具有弹性的雨水管理。然而，在实践中证实肥皂土水力性能的定量证据是有限的。迫切需要这种证据，以便为政府决策和水工业投资提供信息，并支持开发和验证用于规划和设计排水基础设施的建模工具。Severn Trent Water雄心勃勃的曼斯菲尔德全镇肥皂水改造计划提供了一个独特的机会，可以收集关于这些系统在实践中如何运行的关键证据。该项目将主要利用Severn Trent Water已经计划收集的现场数据(下水道内/肥皂液流动和空隙空间水平数据)。此外，我们将集中测量至少一个单独的设备(例如，生物延伸室或“雨园”)，以允许详细的数据收集和建模工具的审查，目标是建议改进肥皂水建模和设计。除了自然降雨事件外，我们还将设计人工降雨/流入该设备的输入，以提供与极端设计降雨事件对应的测试用例数据。
