Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. This Arctic research is needed to inform the economy, security and resilience of the Nation, the larger region and the globe. NNA empowers new research partnerships from local to international scales, diversifies the next generation of Arctic researchers, enhances efforts in formal and informal education, and integrates the co-production of knowledge where appropriate. This award fulfills part of that aim by addressing interactions among social systems, natural environment, and built environment in the following NNA focus areas: Arctic Residents, Education, Forecasting, Data and Observations, and Resilient Infrastructure. Coastal delta communities are among the most vulnerable to climate change, causing most communities to wonder what their lands and waterways will look like in decades to come. State of Alaska reports identify villages of the Yukon-Kuskokwim (YK) Delta as underserved with respect to basic government services and highlight areas threatened by sea level rise, coastal erosion, flooding, and permafrost degradation. Likewise, communities and traditional ways of life are threatened by sea level rise, salinization, and storm surge because of the low elevation of the delta. Additionally, the decrease in duration and extent of coastal sea ice has contributed to greater storm impacts increasing the vulnerability of the YK Delta to coastal hazards. These changes are forcing Alaskan Native communities to face new realities in their day-to-day lives. Changes in the water cycle driven by climate change are generating risks to health, sanitation, and infrastructure. Populations living in rural villages in the YK Delta region experience challenges in the quality, accessibility, and reliability of drinking water and sanitation services. These effects are exacerbated by changes in climate and water budgets that are increasingly influencing water cycles in the Arctic. As communities, like Kongiganak and Mekoryuk navigate the changing Arctic together, it is essential to chart a course that holistically considers the physical and human dimensions of these new realities.This research will: evaluate near-term and far-term prospects of providing safe, affordable, resilient, and locally acceptable drinking water, sanitation, and hygiene services in the context of environmental change (erosion, permafrost thaw, and flood hazards); measure, quantify, and model rates of landscape change and altered hydrology caused by rising sea level and the collapse of permafrost across the built environment and landscapes used for traditional livelihoods; utilize new baseline hydrographic data collected with community partners through bathymetric surveys, water level gauges, and coastal wave buoys to develop high-resolution 3D hydrodynamic models of storm surge flooding delivering predictive flood hazard maps and workflows for other communities; develop the first estimates of water/sanitation-related coping costs for rural Alaskan communities and quantify benefits/costs of various water/sanitation-service delivery models under different landscape and climate scenarios; co-develop community-based monitoring programs that allow for determination of how current rates of environmental change compare to historical trends and Indigenous Knowledge observations. We will document effective convergent workflows/co-production techniques to be applied broadly in the YK Delta and beyond where the same challenges of rapid climate change are playing out.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.

NSF的10个大创意之一是导航新北极（NNA）。 NNA项目应对北极快速变化的融合科学挑战。需要进行这项北极研究，以告知国家，较大地区和全球的经济，安全和弹性。 NNA赋予从本地量表到国际规模的新研究伙伴关系，使下一代北极研究人员多样化，加强了正规和非正式教育方面的努力，并在适当的情况下整合了知识的共同生产。该奖项通过在以下NNA焦点领域中解决社会系统，自然环境和建筑环境之间的互动来实现该目标的一部分：北极居民，教育，预测，数据和观察以及弹性的基础设施。沿海三角洲社区最容易受到气候变化的影响，这使大多数社区想知道他们的土地和水道在未来几十年的样子。阿拉斯加州的报告确定育空库斯科克温（YK）三角洲的村庄在基本政府服务方面不足，并突出了受海平面上升，沿海侵蚀，洪水，洪水和多年冻土降级威胁的地区。同样，由于三角洲的海拔低，社区和传统的生活方式受到海平面上升，盐分和风暴潮的威胁。此外，沿海冰的持续时间和范围的减少导致了更大的风暴影响，从而增加了YK三角洲对沿海危害的脆弱性。这些变化迫使阿拉斯加本地社区在日常生活中面临新的现实。气候变化驱动的水循环变化正在为健康，卫生和基础设施带来风险。居住在YK Delta地区农村村庄的人口在饮用水和卫生服务的质量，可及性和可靠性方面面临挑战。气候和水预算的变化加剧了这些影响，这些变化越来越影响北极的水周期。 As communities, like Kongiganak and Mekoryuk navigate the changing Arctic together, it is essential to chart a course that holistically considers the physical and human dimensions of these new realities.This research will: evaluate near-term and far-term prospects of providing safe, affordable, resilient, and locally acceptable drinking water, sanitation, and hygiene services in the context of environmental change (erosion, permafrost thaw, and flood危害）；测量景观变化和模型的速度变化以及由于海平面上升而改变的水文学，以及用于传统生计的建筑环境和景观中多年冻土的崩溃；利用新的基线水文数据通过测深调查，水位仪和沿海波浪浮标收集的新基线水文数据，开发高分辨率的3D流动动力学模型的风暴潮洪水，为其他社区提供预测性的洪水危险图和工作流程；在不同的景观和气候场景下，开发了针对阿拉斯加农村社区的水/卫生相关应对成本的首次估计，并量化各种水/卫生服务交付模型的福利/成本；共同开发社区的监测计划，允许确定当前环境变化的比率与历史趋势和土著知识观察相比。我们将记录有效的收敛工作流/联合制作技术，该技术将广泛应用于YK三角洲，以及在快速气候变化所面临的相同挑战的范围之外。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来支持的。
