Processing 3D Models of Large Instream Wood for Hydraulics Applications – Structure- from-Motion Workflow Documentation

Creator:: Tutka, Michał
Abstract:: Estimating how large instream wood (LW) may impact local hydraulics is critical both for mitigating flood hazards and for ensuring intended habitat benefits of the LW are produced. In practice, the design of forms such as LW is limited by a lack of mechanistic tools for estimating how LW features...

Understanding Aquifer Water Retention Dynamics Using Groundwater Head Relaxation Time

Creator:: Jimmie, Jordan A.
Abstract:: Diking and channelizing in the Toppenish Creek basin, associated with irrigated agricultural development, has altered its natural ecosystem function and hydraulic processes. We seek to answer two research questions: if surface waters are diverted for aquifer recharge in the winter, will this water be available for ecosystem function in the...

Modeling the Influence of Wildfire Management Networks in Social-Ecological Systems

Creator:: Avila, Colton C.
Abstract:: Wildfire management networks allow for collaborative intervention in mitigating the ever-present risk of major wildfire events. This thesis consists of two manuscripts that explore the topology and characteristics of wildfire management networks and their ability to influence wildfire severity in social-ecological systems. The first manuscript focuses on the characteristics of...

A land application treatment strategy for landfill leachate and water reclamation

Creator:: White, Steven G.
Abstract:: The objective of this study is to evaluate the potential of removing organic carbon and inorganic nitrogen contaminants, and metals from the leachate prior to any land application. New guidelines are needed to ensure the environment and our health is not put at risk. The cost of installation, operation and...

Database of detailed costs of dam removals

Creator:: Tullos, Desiree and Bountry, Jennifer
Abstract:: Dam removal is an important management tool for addressing aging infrastructure, public and structural safety, restoration of river connectivity for migratory organisms and recreation, and habitat quality. However, planning for dam removals is constrained by the difficulty of cost estimation. To our knowledge, published data on dam removal plans, total...

Leveraging the Food-Energy-Water Nexus for Planet Resilience

Creator:: Steadman, Casey L.
Abstract:: We have sufficient evidence that our historical management of natural resources is not sustainable. Food production is stagnating or declining. Nonrenewable energy sources on which the energy sector has historically depended are being rapidly depleted. Water resources, for which the energy and food sectors compete, are being depleted and impaired....

Streamwater Microbial Communities as Hydrologic Observation: Insights Gained from Investigation of a Novel Dataset

Creator:: URycki, Dawn R.
Abstract:: Interactions and feedbacks among climate change effects and continued human impacts will exacerbate impacts to water resources in complex ways. An urgent imperative of the hydrologic community is to understand the response of hydrologic systems to these perturbations, thus contributing to long-term sustainability of water resources in an uncertain future....

Feasibility of Thermal Restoration by Groundwater Additions in the Middle Fork John Day

Creator:: Hale, Abigail E.
Abstract:: Survival of ecological systems pivot on critical moments. In the arid John Day Basin of Eastern Oregon, extensive restoration of the stream and floodplain focused on supporting salmon has been ongoing for the past 20 years, but recurring short periods of extreme temperature increase and low flows result in mortality...

A Statistical Method for Generating Temporally Downscaled Geochemical Tracers in Precipitation

Creator:: Finkenbiner, Catherine E., Good, Stephen P., Allen, Scott T., Fiorella, Richard P., and Bowen, Gabriel J.
Abstract:: Sampling intervals of precipitation geochemistry measurements are often coarser than those required by fine-scale hydrometeorological models. This study presents a statistical method to temporally downscale geochemical tracer signals in precipitation so that they can be used in high-resolution, tracer-enabled applications. In this method, we separated the deterministic component of the...

Development of a Statistical Emulator of US Crop Yields via a Deep Neural Network Approach

Creator:: Proctor, Kyle W.
Abstract:: Agricultural systems are inherently complex; understanding these systems requires knowledge of climatology, plant physiology, soil physics, economics, and the human psychology of the farmers themselves. Decision support tools strive to leverage existing data to help guide stakeholders towards the best policies and practices for their situation. Quantitative crop simulation models...
