Autonomous in situ measurements of estuarine surface PCO₂ : instrument development and initial estuarine observations

Creator:: Wall, Colleen McKay
Abstract:: A novel, low-cost instrument capable of measuring surface water PCO₂ was designed for use in dynamic, shallow-water environments. The instrument was tested in the Yaquina River Estuary, a macrotidal estuary known to experience a wide range of conditions ranging from dominance by the coastal ocean during summer upwelling to substantial...

Make it Rain : A Lagrangian Approach to Investigate Land Surface Controls on Moisture Recycling in the Columbia River Basin

Creator:: Tai, Leah Chung-Mei
Abstract:: Linkages between land use and its influence on the atmosphere have been a long-standing research area. For example, what is the impact of irrigated agriculture on downwind rainfall? Global-scale models show that moisture recycling is an important source of water for inland regions around the world, but they do not...

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...

Development of a two-dimensional hydraulic model to evaluate sediment deposition after the Klamath dam removal

Creator:: Marx, Abigail
Abstract:: After over two decades of advocacy and planning, the four hydroelectric facilities on the Klamath River will be decommissioned and removed starting in 2023. Significant positive changes are expected to result, from reduced severity of Harmful Algal Blooms (HABs) to nearly a two-fold increase in accessible habitat for native salmonid...

Lamb growth and pasture production in agrivoltaic production system

Creator:: Andrew, Alyssa C.
Abstract:: Grasslands and croplands located in temperate agro-ecologies are ranked to be the best places to install solar panels for maximum energy production. Therefore, agrivoltaic systems (agricultural production under solar panels) are designed to mutually benefit solar energy and agricultural production in the same location for dual-use of land. However, both...

Sensitivity and Partitioning in Remote Sensing Based Evapotranspiration Models

Creator:: Talsma, Carl J.
Abstract:: Satellite Based evapotranspiration (ET) models have become a dominant means to estimate large-scale surface fluxes of water. Global and regional ET estimates are important parameters in many climate forecasts and hydrologic models. However, large scale partitioning of ET into soil evaporation, transpiration, and canopy interceptions remains largely unknown and modeled...

Proposal of an Automated Workflow for Appropriate Tile Drainage Simulation in Denitrifying Bioreactor Planning and Design

Creator:: Grohman, Travis A.
Abstract:: Denitrifying bioreactors are an edge-of-field treatment technology particularly well suited for nitrate removal from subsurface (tile) drainage effluent of agricultural lands. The effectiveness of a proposed denitrifying bioreactor is site-specific and depends upon the complicated interplay of field and environmental parameters controlling discharge events, nitrate concentrations, subsurface temperatures, dissolved oxygen...

Physical Modeling of the Feedbacks Between a Reed Canarygrass (Phalaris arundinacea) Patch, Hydraulics, and Bedform Evolution

Creator:: Elliott, Susan H.
Abstract:: Reed Canarygrass (RCG) is an aggressive invader in aquatic ecosystems that swiftly modifies the environment and decreases biodiversity. A physical model was used to investigate the mechanisms by which RCG spreads. Experimental trials were implemented to examine feedbacks between a mid-channel patch of the flexible RCG, hydraulics, and bedform evolution...

The Global Consumption Speeds of Premixed Large-Hydrocarbon Fuel/Air Turbulent Bunsen Flames

Creator:: Fillo, Aaron Jesse
Abstract:: Large-hydrocarbon fuels are used for ground and air transportation because of their high energy-density and will be for the foreseeable future. However, combustion of large-hydrocarbon fuels in a turbulent environment is poorly understood and difficult to predict. The turbulent flame speed, which is the velocity at which a flame front...

Experiences in implementing the White Method : estimating evapotranspiration using fluctuations of water table elevation

Creator:: Kollen, Jacob K.
Abstract:: Evapotranspiration (ET) is the process by which water is transferred from land to the atmosphere. ET is the second most important component of a hydrologic budget and remains difficult to estimate. The primary objective of this project was to determine the limitations of estimating ET from water table elevation fluctuations...
