Behavior of a compliant wave-current barrier

Creator:: Kerper, Dale R.
Abstract:: This study includes an analytical solution to the wave-current barrier interaction problem and large scale experiments to validate the theory. The boundary value problem is solved mathematically by characterizing the flow field and barrier motion separately, then coupling the relationships with the appropriate kinematic and dynamic boundary conditions. The flow...

An efficient high-performance computing based three-dimensional numerical wave basin model for the design of fluid-structure interaction experiments

Creator:: Nimmala, Seshu B.
Abstract:: Fluid-structure interaction (FSI) is an interesting and challenging interdisciplinary area comprised of fields such as engineering- fluids/structures/solids, computational science, and mathematics. FSI has several practical engineering applications such as the design of coastal infrastructure (such as bridges, levees) subjected to harsh environments from natural forces such as tsunamis, storm surges,...

Wave modeling at the mouth of the Columbia River

Creator:: Kassem, Sarah
Abstract:: As the second largest river in the U.S., the entrance to the Columbia River is home to some of the most extreme wave conditions on the Pacific Coast. Winter storms commonly generate waves 6-8 m in height, which in combination with strong tidal currents, can produce dangerous navigation conditions. To...

Spatial and temporal characteristics of groundwater levels adjacent to beaver ponds in Oregon

Creator:: Sharps, Diana E.
Abstract:: This study was undertaken to evaluate the spatial and temporal characteristics of riparian groundwater tables adjacent to beaver ponds. The research was conducted in two parts; in the first portion a two-dimensional, finite-difference computer model was developed and utilized to simulate groundwater elevations through time in pond-adjacent aquifers. Two types...

Modeling of an Urban Radiocesium Pathway from Catchment to Wastewater Treatment Sludge - Dataset

Creator:: Ng, George M. H.
Abstract:: This archive is a compilation of SWMM input files and STELLA models, augmented by R scripts to perform various processing for sensitivity analysis, data import / export, plot generation and computation of various summary outputs. Part I is the sensitivity analysis of a SWMM model representative of the case study...

Study of interfacial condensation in a nuclear reactor core makeup tank

Creator:: Ma, Chang Chun
Abstract:: Steam interfacial condensation in a core makeup tank was simulated using the code RELAP5/MOD3 version 8.0 to predict the violent pressure oscillation phenomena in a core makeup tank. Six base cases were carried out to study the effects of back pressure and of vacuum conditions produced in the core makeup...

Basin-wide distributed modeling of hydrologic responses to irrigation management in the Wood River Basin, Klamath County, OR

Creator:: Owens, Joshua M.
Abstract:: The Wood River Basin lies upstream of Upper Klamath Lake, the main reservoir of the USBR Klamath Irrigation Project that provides irrigation water to 210,000 acres of downstream land. Water allocation became a contentious issue in 2001 when drought led to curtailment of irrigation deliveries to the Klamath Irrigation Project...

A study of thermal stratification in the cold legs during the subcooled blowdown phase of a loss of coolant accident in the OSU APEX Thermal Hydraulic Testing Facility

Creator:: Wachs, Daniel M.
Abstract:: The phenomena of interest in this work is the thermal stratification which occurs during the early stages of a loss of coolant accident (LOCA) in the OSU APEX Thermal Hydraulic Test Facility, which is a scaled model of the Westinghouse AP600 nuclear power plant. Thermal stratification has been linked to...

The influence of climate change and restoration on stream temperature

Creator:: Diabat, Mousa
Abstract:: Water temperature is an essential property of a stream. Temperature regulates physical and biochemical processes in aquatic habitats. Various factors related to climatic conditions, landscape characteristics, and channel structure directly influence stream temperature. Numerous studies indicate that increased average air temperature during the past century has led to stream warming...
