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...

Evaluation of ECOSTRESS products for estimation of leaf and grape water stress for Southern Oregon vineyards

Creator:: Swafford Steffensen, Collen
Abstract:: Accurate estimation of water stress in vineyards could prove vital for optimizing irrigation and grape quality in a changing climate. The ECOsystem Spaceborne Thermal Radiometer Experiment on the Space Station (ECOSTRESS) offers potential to remotely sense vineyard water stress but lacks validation against in-field measurements in vineyards. In this study,...

¡Sí, Se Puede! Yes, You Can! Employing a Personal Testimonio to Show Young Latinx Students and Families That Their Dreams of College are Well Within Reach

Creator:: Curtis, Lorenzo Michael
Abstract:: From my personal experiences, I’ve noticed that Latinx students and families are most receptive to college-related information communicated as anecdotes. Latinx students are among the most poorly represented demographic at universities nationwide, which I believe can be mitigated through calculated efforts to increase collegiate literacy and understanding. This project is...

Assessing Annelid Habitat Suitability in the Lower Klamath River Basin

Creator:: Corrigan, Rory
Abstract:: This study assessed suitability of annelid habitats under current baseflow conditions and evaluated the mobility of suitable annelid substrates under a 2-year peak flushing flow. Outputs from a 2020 Bureau of Reclamation SRH-2D model were combined with field measurements of annelid presence/absence and habitat variables including depth, velocity and d50,...

Occurrence of beaver (Castor canadensis) in volcanically disturbed lentic habitat

Creator:: Smith, Sierra L.
Abstract:: This study investigates the occurrence of beaver (Castor canadensis) in lentic habitat (lakes and ponds) near Mount St. Helens in Washington, 40 years after the 1980 eruption. At the coarse spatial scale, I surveyed lakes for sign of beaver establishment (lodge or den) across multiple volcanic disturbance zones. At a...

Error Propagation in Sap Flow Measurements Using the Heat Ratio Method

Creator:: Miller, Jackson T.
Abstract:: Accurate estimation of the amount of water used by trees is important for a variety of agricultural applications. There are several current methodologies for measuring sap flow and water use in trees, however the heat ratio method has been identified as the ideal due to its ability to measure low...

Statistically Downscaled Precipitation Water Isotope Time Series at NEON Study Sites

Creator:: Spencer, Lindsey
Abstract:: The National Ecological Observatory Network (NEON) provides open access data products including sub-daily precipitation amounts and biweekly stable water isotope concentrations at sites across the United States. Stable water isotope (ẟ2H, ẟ18O) concentrations are often used in hydrometeorological studies and models, however the relatively infrequent biweekly sampling intervals of NEON...

Terra Cubes Design Final Technical Report: Design of a Modular Bioretention System for Nitrate, Phosphate and Herbicide Treatment

Creator:: Evans, Lucas, Larson, Lars, Debell, Thomas, and Dunstan, Nicholas
Abstract:: Plant nurseries comprise the largest agricultural sector in Oregon at nearly $1 billion per year. Even at this scale, individual nurseries and greenhouses do not have clear water quality standards set by the EPA. Watershed-level total maximum daily loads (TMDLs) have been set for excess nutrients and herbicides due to...

Predicting Watershed Characteristics Using Bacterial DNA

Creator:: Chadwick, Jessica A.
Abstract:: This study was conducted to determine if bacterial DNA present streams could be used to predict upstream watershed characteristics. Previous studies have found that bacterial composition in soil is influenced by land use. It was hypothesized that if the bacteria present in a stream is known that it can be...

Introducing the OPEnS HUB 2.0 - A Versatile, In situ, Remote, Sensor Hub

Creator:: DeBell, Thomas C., Goertzen, Luke, Selker, John, and Udell, Chet
Abstract:: Research in geoscience often requires transmission of significant amounts of data from remote locations. The emergence of microcontrollers and open-source sensors are allowing connectivity to affordable, distributed in-situ monitoring. This report describes the OPEnS Hub, a modular data hub orders of magnitude cheaper than commercial dataloggers when scaled to multiple...
