  • Remote sensing of radiation stress gradients from optical imagery

    Creator:
    Killian, Jason R.
    Abstract:
    Wave-induced circulation is the defining characteristic of the nearshore. Within this region, the constant feedback cycle between incoming waves, wave-generated currents, and the mobile sediment bed is responsible for the evolution of complex patterns in nearshore and beach morphology. Central to our understanding of this system is knowledge of the...

  • Dune erosion models and swash zone kinematics from remote video observations

    Creator:
    Palmsten, Margaret L.
    Abstract:
    The subaerial beach, composed of sand dunes and the foreshore, provides a natural buffer zone between vulnerable land and the dissipation of storm wave energy due to wave breaking. The natural beauty of this region is attractive to people, and as a result, significant investment has been placed in this...

  • Development of 2D models to estimate nearshore bathymetry and sediment transport

    Creator:
    Splinter, Kristen D.
    Abstract:
    We examine the interactions and feedbacks between bathymetry, waves, currents, and sediment transport. The first two pro jects focus on the use of remote sensing techniques to expand our knowledge of the nearshore. Due to the plethora of snap-shot data that is available from satellites and their distribution via Google...

  • The sediment response of a dissipative beach to variations in wave climate

    Creator:
    Haxel, Joseph H.
    Abstract:
    Using wave and wind data from nearby buoys and gauges, real time kinematic global positioning system (RTK-GPS) and light detection and ranging (lidar) topographic survey data, and a robust video record, we have quantified the Large Scale Coastal Behavior (LSCB) of a dissipative end member beach in the Pacific Northwest....

  • Remote measurements of waves and currents over complex bathymetry

    Creator:
    Chickadel, Carmine C. (Carmine Christopher)
    Abstract:
    Waves are the primary input of energy in the nearshore region, and together with the currents forced through the transfer of momentum that occurs during the wave breaking process they are the principal mechanism for sediment transport in the nearshore. The basic physics of waves and currents are thought to...

  • Predicting the longshore-variable coastal response to hurricanes

    Creator:
    Stockdon, Hilary F.
    Abstract:
    The longshore variability of the coastal response to hurricanes may be examined within the framework of a storm-impact scaling model that compares spatially-variable beach morphology and fluid forcing. The relative elevations of dune height and storm-induced water levels are used to define three impact regimes (swash, collision, and overwash), within...

  • Quantitative analysis of nearshore morphological variability based on video imaging

    Creator:
    Alexander, Patricia Soupy
    Abstract:
    In the past, classification systems for the analysis of morphodynamic variability have been developed in an attempt to understand large scale coastal behavior. The motivation behind the creation of these classification systems has been to provide a framework of analysis, in order to understand large scale response to seasonal variability,...

  • Using the Rotorwash of a Quadcopter Drone to Remove Dust from a Solar Panel

    Creator:
    Holman, Samantha K.
    Abstract:
    The electrical output of solar panels is reduced when dust covers the panels, but the air movement produced by a flying drone can be used to remove this debris. This research project will study the effectiveness of a quadcopter drone in dusting a solar panel. A solar panel was covered...

  • Adaptation to long-term osmotic stress in a domesticated Saccharomyces cerevisiae strain

    Creator:
    Holman, Douglas S.
    Abstract:
    Osmotic stress is a common challenge faced by organisms in environments with variable salinity or aridity. Understanding the evolutionary mechanisms underlying adaptation to osmotic stress may have wide applications, including management of populations experiencing climate change, or engineering industrial organisms involved in processes such as fermentation. While Saccharomyces cerevisiae is...

  • Load Path Investigation in a Light-Frame Wood House with Complex Geometry

    Creator:
    Holman, Justin D.
    Abstract:
    The objective of this study was to investigate load paths in an existing light-frame wood structure with complex geometry, using previously established computer modeling methods. The structural model is derived from an existing, multi-level residence located in Corvallis, Oregon. For the purpose of this study, the existing structure was simplified...
