Subsurface fluid flow pathways are crucial to critical zone structure and function, but are quickly evolving due to environmental changes, including climate, land use, or regulatory changes. Despite their importance, gaps in identifying, quantifying, and understanding hydraulic pathways and fluxes remain. The goal of my research program is to understand how fluid flow pathways and fluxes from the local to regional scale are evolving due to environmental changes. The short term goals of this research program will result in new methods to evaluate both the evolving fluid flow pathways in temperate and cold regions and the processes that drive them at multiple scales. This will improve our understanding of how environmental change is affecting hydraulic pathways, providing new methods for identifying fluid flow pathways, while training four PhD, three MSc, and five BSc students. Through experiments and surveys, we will examine the interactions of bromine and organic matter using stable bromine and chlorine isotopes, to evaluate evolving fluid flow pathways in cold regions and temperate regions. Evolving fluid flow pathways in cold regions will also be investigated using barometric response functions. A framework will be developed to target, obtain, and evaluate data from large publicly accessible databases to identify and evaluate how changing environmental conditions are affecting fluid flow pathways in temperate regions. Results from this research program will advance our ability to characterize and understand the shifting hydraulic pathways resulting from environmental change. This knowledge will help provide the data necessary to improve water availability outcomes resulting from land use, climate, and regulatory changes. HQP, trained as hydrogeologists and biogeochemists, will improve professional skills, scientific literacy and communication, and will be prepared to contribute in a wide variety of geoscience careers.

地下流体流动通道对关键区域的结构和功能至关重要，但由于环境变化，包括气候，土地使用或监管变化，这些通道正在迅速演变。尽管它们的重要性，在识别，量化和理解水力路径和通量的差距仍然存在。我的研究计划的目标是了解如何从本地到区域规模的流体流动路径和通量是由于环境变化而演变的。该研究计划的短期目标将导致新的方法来评估温带和寒冷地区不断变化的流体流动路径以及在多个尺度上驱动它们的过程。这将提高我们对环境变化如何影响液压路径的理解，为识别流体流动路径提供新方法，同时培训四名博士，三名硕士和五名理学士学生。通过实验和调查，我们将使用稳定的溴和氯同位素来研究溴和有机物的相互作用，以评估寒区和温带地区不断演变的流体流动路径。还将使用气压响应函数研究寒冷地区的流体流动路径。将制定一个框架，以确定目标，获取和评估来自大型公开数据库的数据，以确定和评估不断变化的环境条件如何影响温带地区的流体流动路径。这项研究计划的结果将提高我们的能力，以表征和理解的变化液压路径所造成的环境变化。这些知识将有助于提供必要的数据，以改善土地利用、气候和监管变化带来的水资源可用性结果。HQP，作为水文地质学家和地球化学家的培训，将提高专业技能，科学素养和沟通，并将准备在各种各样的地球科学事业作出贡献。
