Risk and return on investment tool (RROIT)

由于城市化和气候变化，城市环境中与水有关的问题正在加剧。与水有关的城市环境问题的一个主要方面是与造成许多影响的极端风暴有关，包括侵蚀、导致令人担忧的污染物进入水体的陆上流动、洪水问题(例如地下室洪水和对健康的影响)、绕过废水处理等，清单还在继续。然而，尽管人们意识到了这些担忧，但在如何引入有效的方法将其纳入决策中存在重大挑战，即产生风险的问题。本研究项目将侧重于令人关注的污染物(POCs)，并开发将风险维度纳入决策的算法，包括改进评估以纳入风险要素的适当措施。这项研究的结果将包括制定应对洪涝灾害的战略和有效的管理办法，以改善洪灾地区的水质(例如，通过有效投资(消除一些风险)，防止或至少减少对健康的影响)。结果还将包括一系列措施，以便在发生事件时改善技术的性能(例如，雨水池及其维护)。这项研究将制定适当的方法，帮助确定现有知识和方法的差距，并在名为RROIT或“风险和投资回报工具”的工具中改进方法，该工具是一个正在建设的工具，旨在帮助市政当局/顾问做出基于证据的成本效益决策，以减少洪水风险。

Water-related issues in the urban environment are intensifying as a result of urbanization and climate change.A major dimension of the water-related concerns for the urban environment is in relation to extreme stormswhich are causing many impacts, including erosion, overland flow resulting in pollutants of concern enteringwaterbodies, flooding dimensions (e.g. basement flooding and health effects), wastewater treatment bypasses,and the list continues. However, although there is awareness of the concerns, there are major challengesrelated to how to introduce effective methodologies that will incorporate into decision-making, the issues of theresulting risks.This research project will focus on the pollutants of concern (PoCs) and develop algorithms for incorporatingthe dimensions of risk into decision-making, including appropriate measures to improve the assessments toincorporate the elements of risk. The results of the research will include the development of strategies foreffective management options to improve water quality within flooded areas (e.g. by effectively investing(removing some of the risks) by preventing or at least decreasing, the health impacts from occurring). Theresults will also include an array of measures to improve the performance of technologies when an event doesoccur (e.g. stormwater ponds and maintenance thereof). This research will develop appropriate methodologiesto help identify gaps of knowledge and methodologies that currently exist, and refine the methodology withinthe tool entitled RROIT or the 'risk and return on investment tool', a tool which is being constructed to helpmunicipalities/consultants to make evidence-based cost-effective decisions to reduce flood risks.
