项目摘要

This Boosting Research Ideas for Transformative and Equitable Advances in Engineering (BRITE) Pivot award will fund research that enables the intelligent deployment of optimal strategies for mitigating the damaging effects of rain-induced flooding, thereby promoting the progress of science and advancing the national prosperity, welfare, and health. Climate change is causing more frequent extreme weather events, like heavy rains, with disastrous consequences to infrastructure, public health, and national security. As the population grows and new urban centers develop, flood mitigation becomes a complex task that requires high-level coordination, is time critical, occurs in the presence of uncertainty and lack of full observability, and may be only partially feasible due to infrastructure constraints. This project will build a control framework powered by artificial intelligence to operate reservoirs in an optimal way for regulating streamflow while accounting for incomplete data acquisition, unpredictable effects of extreme weather, and ethical decision-making. The results from this research will benefit the scientific communities of hydrologic systems, control, and robotics, with applications also to intelligent systems with machine ethics. In addition, this project will provide undergraduate research opportunities and outreach activities, including educational materials for K-6 students to learn how climate change affects people’s lives, with emphasis on enhancing diversity, equity, and inclusion.This research aims to make fundamental contributions to methods for combining physics-informed and recurrent neural networks to predict the evolution of dynamic systems while also quantifying the effects of uncertainty, as well as for constructing learning-based control synthesis algorithms for complex high-level tasks that are temporally constrained and potentially infeasible in a partially observable environment. Data collected from US Geological Survey stations will be used to parameterize hillslope-link hydrologic models for streamflow forecasts. Small model simulations will then be combined with machine learning techniques to forecast streamflows with uncertainty quantification. Next, a formal description of the flood mitigation task that also accounts for lack of observability will be used to characterize the cost of violating temporal and economic constraints and ethical preferences. Finally, reinforcement learning techniques will be used to train a control agent to intelligently accomplish infeasible tasks to the greatest possible degree. A case study of the flood of 2008 of the Iowa-Cedar Watershed will be used to demonstrate the model development and control framework.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项促进工程变革和公平进步的研究理念（BRITE）支点奖将资助能够智能部署最佳策略的研究，以减轻降雨引发的洪水的破坏性影响，从而促进科学进步，促进国家繁荣、福利和健康。气候变化正在导致更频繁的极端天气事件，如暴雨，给基础设施、公共卫生和国家安全带来灾难性后果。随着人口的增长和新城市中心的发展，防洪成为一项复杂的任务，需要高水平的协调，时间紧迫，发生在存在不确定性和缺乏完全可观测性的情况下，由于基础设施的限制，可能只有部分可行。该项目将建立一个由人工智能驱动的控制框架，在考虑数据采集不完整、极端天气的不可预测影响和道德决策的情况下，以最佳方式调节水库的流量。这项研究的结果将有利于水文系统、控制和机器人的科学界，也将应用于具有机器伦理的智能系统。此外，该项目将为本科生提供研究机会和外展活动，包括为K-6年级学生提供教材，以了解气候变化如何影响人们的生活，重点是加强多样性、公平性和包容性。本研究旨在为结合物理信息和循环神经网络的方法做出基础贡献，以预测动态系统的演变，同时量化不确定性的影响，以及为复杂的高级任务构建基于学习的控制综合算法，这些任务在时间上受到限制，并且在部分可观察的环境中可能不可行。从美国地质调查局站收集的数据将用于参数化山坡连接的水文模型，用于流量预报。然后，小型模型模拟将与机器学习技术相结合，以不确定性量化预测流量。接下来，对洪水缓解任务的正式描述也考虑到缺乏可观察性，将用于描述违反时间和经济约束以及道德偏好的成本。最后，将使用强化学习技术来训练控制代理，以最大程度地智能完成不可行的任务。以2008年爱荷华-雪松流域的洪水为例，演示模型开发和控制框架。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
