项目摘要

This research will develop an approach to optimize investment decisions to improve urban storm water system resilience to forecasted extreme weather events. Many cities already struggle with storm water pipes that are in poor condition and are undersized relative to changing weather patterns. Green infrastructure is recommended as a "low regret" strategy to reduce flooding while also providing co-benefits to freshwater provision, ecological processes, and freshwater fish populations. The question remains, however, as to how to allocate investments under environmental uncertainty. This research will formulate approaches that allow decision-makers to evaluate trade-offs in storm water infrastructure investment. The research team aims to increase gender and ethnic diversity in STEM by collaborating with various campus-wide student chapters of minority organizations, such as the Tennessee Louis Stokes Alliance for Minority Participation, to recruit underrepresented students to pursue degrees in engineering. Although more frequent and intense weather events are projected for many locations, the exact timing and effects of such events are uncertain. This research will provide a scientifically informed approach to evaluate the consequences of making infrastructure planning decisions under this uncertainty, and showcases the power of this approach to obtain and evaluate optimal green infrastructure placement. Here, the team will: (1) develop a novel framework that can incorporate predictions from a variety of weather prediction models, (2) use a semi-distributed, well calibrated, hydrologic model to evaluate the response of a storm water system to these scenarios by identifying the vulnerability of the system to flooding, (3) adopt sophisticated mathematical methodologies, including stochastic programming and robust optimization, to account for the uncertainties in weather patterns over a long planning horizon, and (4) optimize green infrastructure placement within the storm water system to maximize flood resiliency under climate uncertainties, subject to various economic, physical, and social constraints.

这项研究将开发一种优化投资决策的方法，以提高城市雨水系统对预测的极端天气事件的抵御能力。许多城市已经在与雨水管道作斗争，这些管道状况不佳，而且相对于不断变化的天气模式来说尺寸过小。绿色基础设施被建议作为一种“低遗憾”战略，以减少洪水，同时为淡水供应、生态过程和淡水鱼类种群提供共同效益。然而，问题仍然是在环境不确定的情况下如何分配投资。这项研究将制定一些方法，使决策者能够评估雨水基础设施投资的权衡。该研究团队旨在通过与田纳西州路易斯斯托克斯少数族裔参与联盟等少数族裔组织的各个校园学生分会合作，招募代表性不足的学生攻读工程学位，从而增加 STEM 中的性别和种族多样性。尽管预计许多地点将出现更加频繁和强烈的天气事件，但此类事件的确切时间和影响尚不确定。这项研究将提供一种科学的方法来评估在这种不确定性下做出基础设施规划决策的后果，并展示这种方法获得和评估最佳绿色基础设施布局的力量。在这里，该团队将：（1）开发一个新颖的框架，可以整合各种天气预报模型的预测，（2）使用半分布式、经过良好校准的水文模型来评估雨水系统对这些天气的响应通过识别系统对洪水的脆弱性，（3）采用复杂的数学方法，包括随机规划和鲁棒优化，以考虑长期规划范围内天气模式的不确定性，以及（4）优化绿色基础设施在区域内的布局雨水系统最大限度地发挥洪水作用气候不确定性下的弹性，受到各种经济、自然和社会约束。
