NERC-NSFGEO SMARTWATER: Diagnosing controls of pollution hot spots and hot moments and their impact on catchment water quality

这是一个由国家科学基金会地球科学局(NSF/GEO)和英国国家环境研究委员会(NERC)通过NSF/GEO-NERC牵头机构协议共同资助的项目。该协定允许美国和英国提交一个单一的联合提案，并由该机构进行同行审查，该机构的调查员在预算中所占比例最大。在成功地共同确定一项奖项建议后，每个机构将资助其各自国家机构中支持科学家的预算比例。河流水污染对人类和环境健康、经济繁荣和水安全都有影响。遥感和数据科学的最新进展为逐步改变用于识别和理解复杂地貌中水污染的来源、动态和后果的方法提供了前所未有的机会。拟议的“SmartWater”项目将在实验分析、数据科学和数学建模方面产生创新，以新的机制理解在不断变化的水世界中多污染物污染热点(位置)和热点时刻(时间)的动态驱动因素。SmartWater将环境感知、机器学习和数学建模与利益相关者的流域知识相结合，以改变我们诊断、理解、预测和管理水污染热点和热点时刻的方式。SmartWater将为改进决策支持和水质管理框架提供基础，这些框架将由合作伙伴利益相关者共同开发和实施。SmartWater的多学科、NERC-NSF合作团队将结合下一代水污染监测、大数据分析、数值模型和流域知识，揭示决定水质的复杂物理、化学和生物控制。这种诊断和预测水污染热点和热点出现的新能力，以及流域水质动态和水质管理的结果，将在英国和美国的实验天文台上展示。SmartWater将与利益攸关方社区合作，共同创建成功实施实际和与政策相关的水质管理做法的途径。SmartWater将通过确定非线性污染热点和热点时刻对流域水质动态的影响，直接支持面对区域气候和环境变化的未来管理战略的设计和实施。这将提高对河流流域局部暴露变化以及大规模污染物质量通量及其下游出口的了解。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This is a project jointly funded by the National Science Foundation’s Directorate for Geosciences (NSF/GEO) and the National Environment Research Council (NERC) of the United Kingdom (UK) via the NSF/GEO-NERC Lead Agency Agreement. This Agreement allows a single joint US/UK proposal to be submitted and peer-reviewed by the Agency whose investigator has the largest proportion of the budget. Upon successful joint determination of an award recommendation, each Agency funds the proportion of the budget that supports scientists at institutions in their respective countries. River water pollution has consequences for human and environmental health, economic prosperity, and water security. Recent advances in sensing and data science provide unprecedented opportunities for a step change in the approaches used to identify and understand sources, dynamics, and consequences of water pollution in complex landscapes. The proposed “SmartWater” project will generate innovations in experimental analytics, data science and mathematical modelling to yield new mechanistic understanding of the dynamic drivers of multi-contaminant pollution hotspots (locations) and hot moments (times) in a changing water world. SmartWater will integrate environmental sensing, machine learning, and mathematical modelling with stakeholders' catchment knowledge to transform the way we diagnose, understand, predict, and manage water pollution hotspots and hot moments. SmartWater will provide the basis for improved decision-support and water quality management frameworks, which will be developed with and implemented by partner stakeholders.SmartWater’s multi-disciplinary, NERC-NSF collaborative team will unravel the complex physical, chemical, and biological controls that determine water quality by combining next-generation water pollution monitoring, big data analysis, numerical models, and catchment knowledge. This new capability to diagnose and predict the emergence of water pollution hotspots and hot moments, and outcomes for catchment water quality dynamics and water quality management will be demonstrated at experimental observatories in the United Kingdom and the United States. SmartWater will work with stakeholder communities to co-create pathways for successfully implementing practical and policy-relevant water quality management practices. SmartWater will directly support design and implementation of future management strategies in the face of regional climate and environmental change by determining the impact of non-linear pollution hotspots and hot moments on catchment water quality dynamics. This will improve understanding of changing local exposures in river basins as well as large-scale mass fluxes of pollutants and their downstream export.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.
