Groundwater is a critical resource for society, but information related to its use is limited. The goals of this research are to improve our understanding of where and how much groundwater is used. The research outcomes will be directly relevant to water managers, irrigators, and policy makers, benefiting society. The PI will use Hydrologic Sciences Workshops and Scientist Spotlight activities to integrate research into the education of undergraduate students and into the training of a graduate student. The integrated research and education plan will enhance partnerships with state water agencies and produce data products—groundwater well classifications by the geologic formation they tap, and estimated groundwater use—that will enhance infrastructure for research. The data products have the potential to improve existing water storage and depletion tools, models, and assessments that rely on water-use data to constrain water availability, contributing to broader policy discussions. Through this work, the PI will build upon her track record of science communication by broadly disseminating her research in general media outlets through short videos designed to engage the public and policy makers with scientific findings. The research prioritizes scalable methodologies and dissemination of scientific methods and outputs through open access repositories, which will enable further research beyond the expected outcomes from this work. Humans dominate critical components of the hydrosphere, but their impact is challenging to quantify. In the western United States, where direct human impacts on the terrestrial water cycle are expected to be pronounced, the extraction and integration of data from human systems is critical to characterizing hydrologic fluxes. Using the western United States as a case study, this work will integrate large datasets from human systems with more traditional information used in the hydrologic sciences to meet the following objectives: (i) characterize groundwater wells by the geologic formation they tap; (ii) quantify groundwater withdrawals for irrigated agriculture; and (iii) integrate research with planned educational activities that synergistically train undergraduate students and simultaneously produce research outputs. The research will take a convergent approach, combining the PI’s training in hydrology, water-resources engineering, big-data analytics, and water law to improve understanding of the hydrological cycle by characterizing human access to groundwater. This research has the potential to improve existing tools, models, and assessments of storage and depletion that rely on understanding human impacts on the terrestrial water cycle and that rely on water-use data to constrain water availability.This proposal is co-funded by the Hydrologic Sciences and Education and Human Resources programs in the Division of Earth Sciences.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.

地下水是社会的关键资源，但与其使用相关的信息有限。这项研究的目标是提高我们对使用地下水的地点和数量的理解。研究结果将与水管理者，灌溉者和政策制定者直接相关，从而使社会受益。 PI将使用水文科学研讨会和科学家聚焦活动，将研究生的研究整合到本科生的教育和研究生的培训中。综合研究和教育计划将增强与州水理机构的合作伙伴关系，并生产数据产品（通过他们利用的地质形成和估计的地下水使用的地面水井分类）将增强基础设施的研究。数据产品有可能改善依赖水利用数据来限制水的可用性的现有水存储和部署工具，模型和评估，从而有助于更广泛的政策讨论。通过这项工作，PI将通过她在通用媒体中广泛传播她的科学沟通的记录，通过旨在吸引公众和政策制定者进行科学发现的简短视频。这项研究优先考虑可扩展的方法，并通过开放访问存储库对科学方法和输出进行传播，这将使进一步的研究超出这项工作的预期结果。人类主导了水圈的关键组成部分，但其影响是量化的挑战。在美国西部，人们对人类对陆地水周期的直接影响有望得到证明，从人类系统中提取和整合数据对于表征水文通量至关重要。这项工作将使用美国西部作为案例研究，将人类系统的大型数据集与水文科学中使用的更多传统信息集成在一起，以满足以下目标：（i）通过他们利用的地质形成来表征地下水井； （ii）将灌溉农业的地下水提取数量； （iii）将研究与计划的教育活动进行了整合，该活动协同培训本科生并简单地产生了研究成果。这项研究将采用收敛的方法，结合了PI在水文学，水资源工程，大数据分析和水法方面的培训，以通过表征人类对地下水的机会来提高对水文循环的理解。这项研究具有改善现有工具，模型和对存储和部署的评估的潜力，这些工具，模型和评估依赖于人类对陆地水周期的影响，并依靠水利用数据来限制水的可用性。该提案是由该水文科学和教育和人力资源计划共同融合了地球科学的基础。更广泛的影响审查标准。
