  • The Erosion of Siletz Spit, Oregon

    Creator:
    Rea, Campbell Cary
    Abstract:
    Siletz Bay is a drowned river valley filled with Holocene alluvial and estuarine sediments and is separated from the ocean by a sand spit 3.8 km in length. Since the area was settled by white man in the 1890's, the bay has apparently experienced rapid siltation, due to increased farming...

  • Coastal landslides in northern Oregon

    Creator:
    North, William Benjamin
    Abstract:
    Landsliding is a significant contributor to continuous erosion of the 150-mile northern Oregon coast. Direct loss of land to the sea by landslides occurs along 47 percent of the coast. The remaining 53 percent has minor shifting of sand along depositional areas such as spits and dunes. These minor movements...

  • The Effectiveness of the Emergency Rules of 1998, as Implemented During the Erosion Event in Neskowin Oregon, 1999

    Creator:
    Windrope, Amy
    Abstract:
    The purpose of this research is two-fold: to evaluate the success of the new emergency procedures promulgated in 1998 and to characterize the erosion event that precipitated the emergency during January, February and March 1999. These two purposes support each other and provide a holistic understanding of how emergencies arise...

  • Ocean hazards at Bandon, Oregon and scenario for coastal development

    Creator:
    Torstenson, Roger William
    Abstract:
    The community of Bandon is located on the southern half of the Oregon coast, 140 kilometers north of the California border and 40 kilometers south of Coos Bay (Figure 1). Part of the city occupies the low-lying (average 3-meter elevation) area along the south bank of the Coquille River, while...

  • Coastal hazards and community exposure in a changing climate : the development of probabilistic coastal change hazard zones

    Creator:
    Baron, Heather M.
    Abstract:
    Documented trends in rising sea levels, storminess, and extreme wave heights have the potential to increase the frequency and magnitude of coastal change hazards, increasing risks to coastal infrastructure and environmental resources. Coastal planners and decision makers need information about the impacts of future hazards in order to apply mitigation...

  • Tsunami-induced Soil Instability

    Creator:
    Fischer, Rachael Marie
    Abstract:
    Recent tsunami field surveys from the 2011 Great East Japan Earthquake and Tsunami have recorded numerous examples of tsunami-induced soil instability: significant scour around foundations, foundation failure of piles, and other damage caused by liquefaction. From the observations of soil instability leading to the failure of critical coastal structures, it...

  • Simulating extreme total water levels using a time-dependent, extreme value approach

    Creator:
    Serafin, Katherine A.
    Abstract:
    Coastal flood hazard zones and the design of coastal defenses are often devised using either the maximum recorded total water level (TWL) or a 'design' event such as the 100-year return-level flood, usually projected from observed extreme events. Despite technological advances driving more consistent instrumental records of wave heights and...

  • A geographic information system and remote sensing to support community-based coastal hazards planning in the Netarts Littoral Cell, Oregon

    Creator:
    Revell, David
    Abstract:
    The 14-km long Netarts Littoral Cell, located on the northern Oregon coast, experienced episodic erosion as a result of the severe 1997-98 El Nino and 1998-99 La Nina. The erosion events led to the development of a unique partnership bridging scientists, stakeholders, and various planning agencies. To address these erosion...

  • Beach foreshore response to long-period waves in the swash-zone

    Creator:
    Howd, Peter A.
    Abstract:
    A field experiment designed to test the hypothesis that infragravity and lower frequency waves influence the patterns of erosion and deposition on the beach foreshore has been carried out. The data show coherent fluctuations in the foreshore sediment level which can be related to low frequency wave motions. The fluctuations...
