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，但有关其使用的信息有限。这项研究的目的是提高我们对地下水使用地点和使用量的了解。研究成果将直接关系到水资源管理者，灌溉者和政策制定者，造福社会。PI将利用水文科学研讨会和科学家聚光灯活动，将研究纳入本科生的教育和研究生的培训。综合研究和教育计划将加强与州水务机构的合作关系，并产生数据产品--地下水井按其开采的地质构造分类，以及估计的地下水使用量--这将加强研究基础设施。这些数据产品有可能改进现有的水储存和消耗工具、模型和评估，这些工具、模型和评估依赖用水数据来限制水的供应，从而有助于更广泛的政策讨论。通过这项工作，PI将在其科学传播记录的基础上，通过短视频在一般媒体上广泛传播其研究成果，以使公众和政策制定者参与科学发现。该研究优先考虑可扩展的方法，并通过开放获取知识库传播科学方法和产出，这将使进一步的研究超出这项工作的预期成果。人类主导着水圈的关键组成部分，但其影响难以量化。在美国西部，人类对陆地水循环的直接影响预计会很明显，从人类系统中提取和整合数据对描述水文通量至关重要。这项工作将以美国西部为案例研究，将人类系统的大型数据集与水文科学中使用的较传统的信息结合起来，以实现下列目标：㈠根据地下水威尔斯所采的地质构造来确定其特征; ㈡量化灌溉农业所抽取的地下水;以及（iii）将研究与计划中的教育活动结合起来，以协同方式培养本科生，同时产生研究成果。该研究将采取融合的方法，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，通过描述人类对地下水的获取来提高对水文循环的理解。这项研究有可能改善现有的工具，模型，以及对储存和消耗的评估，这些评估依赖于对人类对陆地水循环的影响的理解，并依赖于用水数据来限制水的可用性。该奖项由地球科学部的水文科学、教育和人力资源项目资助。该奖项反映了NSF的法定使命，并被认为值得支持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。
