  • Sediment accumulation and human impacts in Tillamook Bay, Oregon

    Creator:
    Styllas, Michael N.
    Abstract:
    Tillamook Bay is the second largest estuary on the Oregon coast, and concerns have been raised whether human induced impacts have been responsible for the perceived increase in sedimentation rates during the past century. Major land-use practices within the five watersheds of the Bay include logging, forest fires, the construction...

  • Environmental variables as predictors of fish assemblages in the Tillamook Basin, Oregon

    Creator:
    Rose, Cathleen E.
    Abstract:
    The Tillamook and Kilchis subbasins of the Tillamook Bay watershed (Oregon Coast Range) have differences in geology and land use history and, therefore, varied environmental conditions that could affect fish assemblages. Fifty-two randomly selected wadeable stream reaches in these two subbasins were surveyed for stream habitat and fish assemblage composition...

  • Assessing Coastal Community Adaptation Scenarios in the Face of Climate Change : A Tillamook County, Oregon Example

    Creator:
    Lipiec, Eva
    Abstract:
    Recent coastal disasters (e.g., Hurricane Sandy, Typhoon Haiyan) and chronic issues (e.g., Florida's "nuisance flooding") provide numerous examples of coastal communities struggling to adapt in the face of climate change impacts. Decision-makers and the public alike must reconcile the lack of "fit" between a rapidly changing environment and the effects...

  • A Tale of Two Counties : Exploring Co-Produced Coastal Adaptation Strategies in Tillamook County, OR and Grays Harbor County, WA

    Creator:
    Evans-Wilent, Janan K.
    Abstract:
    Coastal communities throughout the US West Coast and elsewhere are facing the daunting task of preparing for climate change impacts, particularly the hazards from increased flooding and erosion. With sea-level rise, changing storminess patterns, and possible changes to the frequency and severity of major El Niño events, communities are already...

  • Coupled wave and surge modeling of Tillamook Bay, Oregon : extreme events and climate change impacts

    Creator:
    Cheng, Tiffany Kay
    Abstract:
    Estuaries represent the confluence of land and ocean environments and encompass a number of complex interactions amongst tides, winds, offshore waves and the riverine contributions, all of which contribute to total water levels (TWLs). The study of TWLs and the relative weight of its components can assist local communities in...

  • 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...

  • 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...

  • Characterization of fire effects on forest ecosystems in the Tillamook Forest, Oregon

    Creator:
    Chen, Shu-Huei
    Abstract:
    From the 1920's through 1951 several severe fires occurred in the predominantly conifer forest ecosystems of the northern Oregon Coast Range. Of the 211,151 ha. of mapped area, 57 percent was burned. The effects of frequent fires with high severity on forest ecosystems over time at the landscape level is...

  • Economic Analysis of A Road Usage Charge

    Creator:
    Ke, Yue
    Abstract:
    This study evaluates the distributional impacts of an alternative public roads finance method, a road usage charge (RUC) fee, on lower income households and rural households in Oregon. While previous research has relied on the 2001 and 2009 National Household Travel Survey (NHTS), this research will uses the 2011-2013 Oregon...

  • Home range, dispersal, homing and density of the Townsend mole Scapanus townsendii (Bachman) near Tillamook, Oregon

    Creator:
    Giger, Richard D.
    Abstract:
    Home range, dispersal, homing and density of Townsend's mole, Scapanus townsendii (Bachman), were studied during 1964 near Tillamook, Oregon. Additional information on the success of marking and capture techniques and the response of moles to flooding was gathered. This study was initiated to supply information which might aid in the...
