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.

地下水是社会的重要资源，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地下水使用地点和用量的了解。研究结果将直接与水管理者、灌溉者和用水者相关。 PI 将利用水文科学研讨会和科学家聚焦活动将研究融入本科生教育和研究生培训中，该综合研究和教育计划将加强与州水务机构的合作并产生成果。数据产品——地下水根据所开采的地质构造对井进行分类，并估计地下水的使用情况，这将增强研究基础设施，这些数据产品有可能改进依赖用水数据来限制用水的现有储水和消耗工具、模型和评估。通过这项工作，PI 将通过短视频在一般媒体上广泛传播她的研究成果，以吸引公众和政策制定者了解研究重点。可扩展的方法和传播通过开放获取存储库来收集科学方法和成果，这将使进一步的研究超出这项工作的预期成果。人类主导了水圈的关键组成部分，但在美国西部，人类对这些地区的直接影响难以量化。由于陆地水循环预计将很明显，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，这项工作将以美国西部为案例研究，将整合来自人类系统的大型数据集和更传统的信息。在水文科学，以实现以下目标：（i）通过地下水井开采的地质构造来表征地下水井；（ii）量化灌溉农业的地下水抽取量；（iii）将研究与计划的教育活动相结合，协同培训本科生并同时进行研究该研究将采取聚合方法，结合 PI 在水文学、水资源工程、大数据分析和水法方面的培训，通过描述人类对水文循环的了解来提高对水文循环的了解。这项研究有可能改进现有的储存和消耗工具、模型和评估，这些工具、模型和评估依赖于了解人类对陆地水循环的影响，并依赖于用水数据来限制水的可用性。该提案是共同资助的。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
