项目摘要

Many areas in the western United States are experiencing a warming climate and more frequent extreme weather conditions such as drought. These changing weather patterns could affect how much of the precipitation flows into streams (becoming stream water) and seeps into the subsurface (becoming soil water and/or groundwater) in mountainous areas. To better manage future water resources, it is critical to understand how a watershed responds to climate change regarding the partitioning of precipitation into stream water, soil water, and groundwater. This project will focus on quantifying various water storages and fluxes at different elevations in a semi-arid watershed in the western United States. Both field tests and computational simulations will be performed. The collected scientific data and developed computational models in this project will contribute to an improved understanding of how the water resources in the mountains respond to climate change. In addition, this project will also encompass significant educational activities, including offering geoscientific field skill training to financially disadvantaged/nontraditional students and providing research experiences to undergraduates on water resources-related issues. This project focuses on how the subsurface water storage buffers the hydrologic process along the elevation gradient in mountainous watersheds. The knowledge gained will help stakeholders effectively manage future water resources in mountainous areas, especially in a warming climate. Following the data-model fusion principle, the project will integrate geophysical data into hydrologic modeling to achieve an improved quantification of various water fluxes and storages in catchments at different elevations in an experimental watershed in southern Idaho. In the field, seismic refraction tests and electrical resistivity monitoring will be performed to characterize the complex subsurface structural heterogeneity and to estimate subsurface water storage dynamics. These field geophysical data will be incorporated into integrated hydrologic modeling to reveal the potential buffering role of subsurface water storage in watershed functions. The educational goal of this project is to promote inclusivity in geoscientific field skills training. A commuter field camp will be offered to accommodate local students and students with personal and financial barriers. A vertically integrated project program will be developed to broaden the participation of undergraduates in water resources-related research at Boise State University. This project will also provide a graduate intern position for students to learn state-of-the-art geophysical techniques and their applications in hydrologic sciences.This award is co-funded by the Hydrologic Sciences program and Established Program to Stimulate Competitive Research (EPSCoR).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.
美国西部的许多地区正在经历气候变暖和更频繁的极端天气条件,如干旱。这些不断变化的天气模式可能会影响有多少降水流入河流(成为河水),并渗入山区的地下(成为土壤水和/或地下水)。为了更好地管理未来的水资源,关键是要了解流域如何响应气候变化,将降水分为溪流水,土壤水和地下水。该项目将侧重于量化美国西部半干旱流域不同海拔高度的各种水储存和通量。将进行现场测试和计算机模拟。该项目收集的科学数据和开发的计算模型将有助于更好地了解山区水资源如何应对气候变化。此外,该项目还将包括重要的教育活动,包括为经济困难/非传统学生提供地球科学领域的技能培训,并为本科生提供与水资源有关的问题的研究经验。该项目的重点是如何地下蓄水缓冲沿着海拔梯度在山区流域的水文过程。所获得的知识将有助于利益攸关方有效管理山区未来的水资源,特别是在气候变暖的情况下。根据数据模型融合原则,该项目将把地球物理数据纳入水文建模,以更好地量化爱达荷州南部一个实验流域不同海拔的集水区的各种水通量和蓄水量。在实地,将进行地震折射测试和电阻率监测,以确定复杂的地下结构不均匀性的特征,并估计地下水储存动态。这些实地地球物理数据将纳入综合水文建模,以揭示地下水储存在流域功能中的潜在缓冲作用。该项目的教育目标是促进地球科学领域技能培训的包容性。将提供一个通勤野外营地,以容纳当地学生和有个人和经济障碍的学生。将制定一个纵向综合项目方案,以扩大博伊西州立大学本科生对水资源相关研究的参与。该项目还将为学生提供一个研究生实习生职位,以学习最先进的地球物理技术及其在水文科学中的应用。该奖项由水文科学计划和刺激竞争性研究的既定计划(EPSCoR)共同资助。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查进行评估,被认为值得支持的搜索.
