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...

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,...

From Perception to Planning : Adaptation in Flood-risk Communities

Creator:: Gomez, Luis A.
Abstract:: This research asserts that flood risk perception of individuals living in floodplains influences their preparedness for taking actions to protect themselves from flood hazards. The results of this research are backed up by quantitative analysis of survey responses of individuals living in floodplains of Corvallis, OR in the USA. The...

Nutrient Transport Conditions in the Ecuadorian Andes

Creator:: Bomeisl, Lauren
Abstract:: This study examines different fate and transport processes of N and P based on uncultivated grass, contour crop, and livestock management across different topographies (i.e. 5% vs. 30% slope) found within the tropical mountains of volcanic pedogenesis in the Ambato river catchment. The hydrologic, cultural, and agricultural properties of the...

Tradeoffs and Preferences between Flood Mitigation Measures

Creator:: Byron, Elizabeth G.
Abstract:: Floods remain the world’s most destructive natural hazard, despite centuries of efforts to minimize losses. Understanding public preferences for flood mitigation measures, and the impacts of these measures, is key to minimizing flood-induced losses. This study quantified tradeoffs between flood mitigation measures and determined factors that influence public preferences for...

Assessing the Impact of Storm Regime on Remotely-sensed Precipitation Extremes Across the Western Himalaya

Creator:: Stanton, Alan L.
Abstract:: Extreme, flood-producing precipitation events in mountains threaten human life and local and national economies. In the Himalayas, scarce meteorological data historically limited understanding of the underlying processes driving extreme events. However, the capacity to observe, measure and quantify precipitation on regional scales has increased tremendously over the last three decades...

Hydrogeography of Cloudburst Flooding in the Himalaya

Creator:: Michelsen, Sonja
Abstract:: Even though cloudburst events in high mountain areas can be highly destructive and result in significant losses of life, little is known definitively about these flood events. An exact understanding of the driving processes, typical precipitation rates, and impacts of cloudburst events remain uncertain. This study seeks to advance knowledge...

Water scarcity and reservoir reliability in basins affected by climate and land use change : impacts of hydrogeology, sensitivities, and uncertainties in the Santiam River Basin, Oregon

Creator:: Mateus, M. Cristina
Abstract:: Multipurpose management of hydrosystems face a number of uncertainties related to hydrologic variability and nonstationarity. Anticipated air temperature increases in the Pacific Northwest region are projected to alter the timing and quantity of streamflow associated with precipitation shifting from snow to rain, including shorter winter runoff periods, earlier spring runoff,...

Roughness and geometry effects of engineered log jams on 1-D flow characteristics

Creator:: Valverde, Rachelle S.
Abstract:: The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

Influence of vegetation on streambank hydraulics

Creator:: Czarnomski, Nicole M.
Abstract:: Proper use of vegetation in streambank bioengineering practices requires a comprehensive understanding of the influence of vegetation density on streambank hydraulics. A series of studies were conducted to investigate the relationship between independent variables vegetation density, bank angle, and discharge and dependent variables channel velocity, resistance, turbulence, and shear stress....
