项目摘要
The specific knowledge necessary to predict and manage the fate and transport of contaminants within rivers is currently inadequate. This project will utilize a conceptual river corridor perspective that considers the surface water, near-surface sediments, the flood zone, the hillslope catchment and contributing groundwater aquifers as a continuum. The project will consider the exchange of water, solutes, energy and materials across a range of spatial and temporal scales and across these various compartments. The project focusses on three primary goals: (1) improve our understanding of dynamic exchange processes in the river corridor; (2) develop methods to scale findings from geomorphic features to the reach and network scales; and (3) improve predictive capacity that can be readily implemented without extensive field characterization of sites of interest. Results of this research will improve our ability to predict the transport and fate of contaminants in river corridors, enabling more effective management of water resources. The integrated education and research plans will inspire a diverse group of K-12 and undergraduate students to pursue careers in STEM fields. The project goal is to develop an integrated program of research and education focused on advancing the understanding of hydrologic exchange in river corridors and the associated ecosystem services and functions. The project will utilize a river corridor perspective that considers the surface stream, its hyporheic zone, riparian zone, hillslope, and aquifer as a continuum, exchanging water, solutes, energy and materials across a range of spatial and temporal scales. The proposed research will quantify spatial and temporal heterogeneity in river corridor exchange at the scale of individual geomorphic features and study reaches, and will synthesize results to develop predictive relationships of river corridor exchange along naturally occurring gradients in geologic setting and under hydrologic forcing. This research will specifically address three research questions: (1) What relatively static characteristics of geologic setting and hydrologic forcing cause predictable variation in river corridor exchange?; (2) To what extent is river corridor exchange controlled by the dynamic interaction between geologic setting and hydrologic forcing?; and (3) How transferrable are predictive relationships and models of river corridor exchange? Research efforts are integrated with educational activities including K-12 education, mentoring high-school and undergraduate researchers, and teaching courses on River Corridor Science and Management at the graduate level.
预测和管理河流内污染物的命运和运输所需的具体知识目前是不足的。该项目将利用一个概念性的河流走廊视角,将地表水、近地表沉积物、洪水带、山坡集水区和贡献地下水含水层视为一个连续体。该项目将考虑水、溶质、能源和材料在一系列空间和时间尺度上的交换,并跨越这些不同的隔间。该项目主要有三个主要目标:(1)提高我们对河流走廊动态交换过程的理解;(2)发展从地貌特征到河段尺度和网络尺度的研究方法;(3)提高预测能力,无需对感兴趣的地点进行广泛的现场表征即可轻松实施。这项研究的结果将提高我们预测河流廊道中污染物的运输和命运的能力,从而更有效地管理水资源。综合教育和研究计划将激励不同群体的K-12和本科生在STEM领域追求职业生涯。该项目的目标是制定一个研究和教育的综合方案,重点是促进对河流走廊水文交换和相关生态系统服务和功能的理解。该项目将利用河流走廊的视角,将地表流、潜流带、河岸带、山坡和含水层作为一个连续体,在一定的空间和时间尺度上交换水、溶质、能量和材料。本研究将在单个地貌特征和研究河段尺度上量化河流廊道交换的时空异质性,并综合研究结果,建立地质环境和水文强迫下自然梯度下河流廊道交换的预测关系。本研究将具体解决三个研究问题:(1)哪些相对静态的地质环境和水文强迫特征导致了河流廊道交换的可预测变化?(2)河廊交换在多大程度上受地质环境与水文动力相互作用的控制;(3)河流廊道交换的预测关系和模型的可转移性如何?研究工作与教育活动相结合,包括K-12教育,指导高中和本科研究人员,以及在研究生阶段教授河流走廊科学与管理课程。
