Sewer system rehabilitation and the effectiveness of chemical grouting

Creator:: Whitaker, Todd B.
Abstract:: The City of Salem, Oregon has an active sewer main chemical grouting program for the control of groundwater infiltration into the sewer collection system. The effectiveness of this chemical grouting program is evaluated by a comparison to other effective chemical grouting programs for control of inflow/infiltration (I/I). The importance of...

Morphodynamic Evolution of Coastal Oregon: Using New Lidar-derived Beach and Sand Dune Morphometrics to Explore Multi-decadal Change

Creator:: Light, Jacob W
Abstract:: The coast of Oregon is highly dynamic, with beach and dune morphodynamics constantly evolving in response to physical and ecological forcing at scales ranging from seconds to decades and meters to tens of kilometers. Evaluating spatial and temporal trends in shoreline evolution is paramount in understanding and eventually developing a...

The Art of Reducing Coastal Hazard Complexity: Coupling Physics and Probability to Understand Extremes, Variability, and Climate-dependence

Creator:: Anderson, Dylan L.
Abstract:: Coastal hazards are the result of numerous physical processes cumulatively causing water levels to flood and erode the land. The waves, storm surges, tides, and run-off contributing to elevated water levels are each the product of chaotic and random weather patterns. These stochastic weather patterns dissipate energy in Earth's climate...

Evaluating climate change induced coastal flood impacts to San Diego Bay Naval Infrastructure - a hybrid statistical dynamical modeling approach

Creator:: Anderson, Tyler P.
Abstract:: This study utilizes probabilistic surrogate modeling techniques around San Diego Bay with an emphasis on naval infrastructure and operations to evaluate the impact of five global mean sea level rise scenarios (GMSLR). Spatially continuous total water levels (TWLs) are combined with a digital elevation model (DEM) of the region to...

Quantifying the Relative Role of the Key Drivers of Coastal Dune Evolution: Observations and Simulations Across a Range of Time and Space Scales in Cape Lookout National Seashore, North Carolina

Creator:: Hovenga, Paige A.
Abstract:: Coastal dunes provide a diverse set of ecosystem services including coastal protection against destructive surge and waves during storm events. Dunes are constantly evolving through various stages of response to storm events and post-storm recovery at rates that vary due to a range of drivers including pre-existing morphology, environmental forcing...

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...

Local scour at isolated obstacles on river beds

Creator:: Huang, Cheng-Chang
Abstract:: Maximum equilibrium scour depths, equilibrium scour volumes, and induced equilibrium movements at isolated obstacles on river beds were investigated in clear-water scour. The research was achieved by a systematic flume study based on the results of dimensional analysis of local scour. The main tested obstacles for local scour were cubes....

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...

A stochastic precipitation event model for use in erosion simulations

Creator:: Istok, J. D.
Abstract:: Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...

Chromium (VI) sorption in soils : chemical behavior and solute transport modeling

Creator:: Schroth, Martin Herbert
Abstract:: Chromium spills on soils are causing severe groundwater contamination problems. To increase the performance of cleanup methods, the chemical behavior of chromium in soils and its transport through soils have to be understood. The objectives of this research were to investigate the sorption characteristics of chromium(VI) in soil and to...
