Consumptive use of surface water by Willamette Basin municipalities

Creator:: Mittelstadt, Richard Lee
Abstract:: The consumptive water use of six cities in the Willamette Basin of northwestern Oregon was evaluated for the period 1960-66. Consumptive use ratios were obtained by analyzing data from monthly water supply and sewage flow records. The average annual consumptive use for the six cities was found to be 26...

Relationships between seasonal suspended sediment behavior and reservoir turbidity

Creator:: Conner, Dan Alan
Abstract:: The causes of turbidity in impounded and released reservoir water are studied. Seven Willamette Basin reservoirs are compared to isolate watershed and reservoir characteristics which produce variations in turbidity. Of the seven, Hills Creek Reservoir is examined in detail. Particular features of the basin and impoundment are studied to isolate...

Frequency and magnitude of bedload transport downstream of the Pelton-Round Butte Dam Complex, lower Deschutes River, Oregon

Creator:: Fassnacht, Heidi
Abstract:: A first-order approximation is made of the frequency and magnitude of bedload transport downstream of the Pelton-Round Butte Dam Complex, lower Deschutes River, Oregon with implications for salmonid spawning habitat. Field measurements of channel hydraulics, geometry, and particle size were combined with one-dimensional hydraulic and bedload transport models to determine...

Prediction of monthly streamflows for Oregon coastal basins using physiographic and meteorological parameters

Creator:: Orwig, Charles Edwin
Abstract:: Prediction equations were developed for estimating the flow regime at ungaged stream locations in the Oregon coastal range. Principal components analysis was used to screen the initial data set of physiographic and meteorological parameters. The final regression equations for predicting mean monthly flow had standard errors of estimate ranging from...

Storm runoff response from roadbuilding and logging on small watersheds in the Oregon Coast Range

Creator:: Hsieh, Frederic Shu-kong
Abstract:: The effects of roadbuilding, logging and burning upon stream runoff responses to individual storms are evaluated for the Alsea experimental watersheds, located in the Oregon Coast Range, The parameters analyzed are peak discharge, induced peak discharge, time-to-peak, and storm-runoff volume. The volume parameter is further sub-divided into total, quick, delayed,...

Tidal influence on downstream fining in gravel-bed rivers

Creator:: Coles, Derron Rafiq
Abstract:: This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

Effects of imbedded perforated pipes on permeability of gravelly stream beds

Creator:: Chu, Eddy Tak-hing
Abstract:: Perforated pipes were buried in the gravel bed of a laboratory stream, extending upstream from a simulated riffle in order to study their effect upon mixing and interchange of stream water and intragravel water. In the absence of such pipes the drop of energy gradient of the stream was concentrated...

Modeling sediment transport, channel morphology and gravel mining in river bends

Creator:: Nam, Ilgi
Abstract:: A technique is developed and tested to analyze the interaction of flowing water, bed topography, and bedload sediment transport in meandering channels where gravel bars are removed. The method relates the local velocity distribution, bed shear stress and sediment transport conditions to the local bed configuration in river bends before...

Predicting channel stability in Colorado mountain streams using hydrobiogeomorphic and land use data : a cost-sensitive machine learning approach to modeling rapid assessment protocols

Creator:: Morét, Stephanie L.
Abstract:: Natural resource data are typically non-linear and complex, yet modeling methods often utilize statistical analysis techniques, such as regression, that are insufficient for use on such data. This research proposes an innovative modeling method based on pattern recognition techniques borrowed from the field of machine learning. These techniques make no...

Incipient resuspension of silt-clay deposits in oscillatory and unidirectional flows

Creator:: Talebbeydokhti, Nasser
Abstract:: Incipient motion of cohesive sediment and the role of flow parameters were investigated for separate and combined unidirectional and oscillatory flows. Sediment from Sturgeon Lake, mainly silt and clay with organic matter, was used as bed material In recirculating and wave flumes. Bench-type experiments indicated that when the submerged sediment...
