  • Direct Shear Interface Friction and Linear Motion Shaking Response of Ecoroofs

    Creator:
    Kilroy, Kimberly A.
    Abstract:
    Ecoroofs have become more prominent in recent years. However, there is currently no enforceable standard or building code for the design and construction of ecoroofs across the United States (Kraupa, 2014). Further research is needed to determine how ecoroofs respond to roof motion and to develop an appropriate design standard.The...

    Abstract:
    Research was conducted to determine the applicability of using the theory of regionalized variables or geostatistics in characterizing the spatial variability of reference evapotranspiration (ETr) over various climatic regimes for the state of Oregon. The state was divided into five climatic regions based on topographic features and local meteorological conditions:...

    Abstract:
    Daily evaporative flux and meteorological data from three sites were collected and analyzed. Analysis included evaluation of several reference evapotranspiration estimating methods which were theoretically based on distinct physical laws. The estimating methods included pan evaporation, energy-based Priestly-Taylor, and combination methods with and without biological adjustments. The data set represented...

    Creator:
    Lee, Jae-Hyuk
    Abstract:
    This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...

  • Laboratory Observations of Tsunami-Driven Debris Damming with Comparison to ASCE 7-22 Minimum Design Loads

    Creator:
    Doyle, Kellen C.
    Abstract:
    Tsunami inundation of coastal communities can impose a wide array of forces on the built environment. Forces generated by tsunami-driven debris damming have the potential to cause failure of coastal structures and further accumulate flow-entrained debris. Since tsunami-resilient design standards were adopted by ASCE in 2016, debris damming considerations have...

    Abstract:
    The circular wave basin provides a means of physically modeling the nearshore without the typical problems associated with end walls. Three different coastal processes were examined to demonstrate the use of a spiral wavemaker in a circular wave basin. These were longshore currents, shear waves, and groin circulation. A beach...

    Abstract:
    A theory is developed to provide an analytical solution to an unsteady flow field which is partially occupied by a porous structure. The flow is induced by a small amplitude incident wave train. The porous structure may contain multi-layer anisotropic but homogeneous media. Three typical porous structures are investigated: a...

    Creator:
    Harper, Spencer H.
    Abstract:
    Synthetic-aperture radar (SAR) imagery can provide wavenumber and frequency data to generate bathymetry estimates for locations where limited access or extreme ocean conditions can make standard bathymetry survey techniques difficult or impossible. The availability of SAR data could allow for regular bathymetry estimates of navigational channels providing insight into dredging...

    Abstract:
    Random waves are often expressed as a mathematical superposition of an infinite number of sinusoidal components. The mean square spectral density of the water surface elevation is often called the wave spectrum. The zero upcrossing wave heights usually have a Rayleigh probability distribution. However, the design wave concept is still...

  • Evaluation of ocean wave-induced liquefaction in a large scale wave flume

    Creator:
    Thielen, David Leo
    Abstract:
    Ocean waves propagating over cohesionless seabed deposits produce cyclic shear stresses within the deposit. Under certain conditions these stresses may cause a progressive build-up of pore pressure. Pore pressure accumulation can result in liquefaction or a substantial decrease in the effective stress with attendant large deformations of the seabed deposit....
