  • 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...

  • Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

    Creator:
    Engleson, Renee M.
    Abstract:
    Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

  • Simulation of coastal processes in a circular wave basin

    Creator:
    Katzev, David H.
    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...

  • Depth-dependence of surf zone eddies : a study at Duck, NC

    Creator:
    Aiken, Rebecca A.
    Abstract:
    Surf zone eddies (f < 0.01 Hz) are important in nearshore mixing, shoreline erosion, the distribution of pollutants, and ecological processes, such as offshore transport of larvae. Surf zone eddies have traditionally been treated as two-dimensional features with horizontal length scales larger than the local water depth. Studies by Lippmann...

  • Field verification of a mathematical model for the physical fate prediction of dredged material instantaneously disposed at sea

    Creator:
    Hollings, William H.
    Abstract:
    Dredged spoil plumes are monitored during nine hopper dredge disposal events in 186 foot water depths offshore near Coos Bay, Oregon. Position and solids volume concentration characteristics of the plumes are established. Computer simulations of the monitored events are executed using the WES modified version of the Koh-Chang instantaneous disposal...

  • Modeling shallow-water hydrodynamics : rotations, rips, and rivers

    Creator:
    Long, Joseph W.
    Abstract:
    Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...

  • Near-Surface Response of Beach Sand : An Experimental Investigation

    Creator:
    Adams, Rachel Katie
    Abstract:
    The near-surface region of a coastal sediment bed is complex and dynamic. At some sites, near-surface sediment deposits are susceptible to extreme events, such as tsunamis or other large overflows, which induce high shear stresses on the sediment bed. The specific properties of sediment beds subjected to such extreme loading...

  • Application of geostatistics to regional evapotranspiration

    Creator:
    Amegee, Kodjo Y.
    Abstract:
    Regionalized variable analysis has been used to study a number of meteorological and hydrological variables including precipitation (Delhomme and Delfinier, 1973), streamfiow (Villeneuve et al., 1979) and hydraulics of groundwater aquifers (Gambolati and Volpi, 1979). In the research work reported in this thesis, an attempt was made to characterize the...

  • Assessment of Environmental Impacts of Wood Substitution in Commercial Construction

    Creator:
    Milaj, Kristina
    Abstract:
    In the residential sector, wood is the predominant construction material. In the commercial sector and in mid‐rise construction, the use of wood is limited because of a multitude of reasons, including building code restrictions, the perception of wood as a structural material, fire code requirements, and lack of knowledge and...

  • Evaluation of the torsion test for determining the shear strength of structural lumber

    Creator:
    Heck, Leanne Renee
    Abstract:
    The torsion test was evaluated as a method for determining the shear strength of full-size structural lumber. The evaluation involved an experimental length study, an experimental depth study, and a finite element study. The length study consisted of fifty nominal 2x4 specimens, ten specimens for each length, and ten American...
