Analysis of rip current embayments on the Oregon coast

Creator:: Dalon, Matthew M.
Abstract:: Understanding the past, present, and future behavior of our nation's shorelines is vital for sensible coastal management. Localized areas of erosion, termed "erosional hot spots", can shift the shoreline landward threatening coastal infrastructure (Kraus and Galgano, 2001; Stauble and Gravens, 2004; McNinch, 2004). One specific type of erosional hot spot...

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...

Beach Dune Subsurface Hydrodynamics and the Formation of Dune Scarps

Creator:: Bond, Hailey G.
Abstract:: The formation of beach scarps is a challenging morphodynamic phenomenon that the coastal community has yet to capture in coastal change models. Understanding scarp formation is crucial to accurately predicting coastal erosion and vulnerability during extreme events, as models without parameters for scarp formation and development severely underpredict total erosion...

Coastal Dune Ecology, Geomorphology, and Ecosystem Services : How Invasive Beachgrasses, their Interactions, and Sediment Dynamics Shape U.S. Pacific Northwest Dunes

Creator:: Biel, Reuben G.
Abstract:: Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the...

Evaluating Coastal Protection Services Associated with Restoration Management of an Endangered Shorebird in Oregon, U.S.A.

Creator:: Carroll, Lindsay J.
Abstract:: Coastal sand dunes and beaches offer a variety of ecosystem services such as coastal protection, sand stabilization, species conservation, and recreation. However, the management and balance of ecosystem services offered by dunes and beaches is challenging when ecosystem services interact across the landscape. Management focusing only on one ecosystem service...

The influence of biophysical feedbacks and species interactions on grass invasions and coastal dune morphology in the Pacific Northwest, USA

Creator:: Zarnetske, Phoebe Lehmann
Abstract:: Biological invasions provide a unique opportunity to study the mechanisms that regulate community composition and ecosystem function. Invasive species that are also ecosystem engineers can substantially alter physical features in an environment, and this can lead to cascading effects on the biological community. Aquatic-terrestrial interface ecosystems are excellent systems to...

The Response and Effect of Emergent Coastal Vegetation to Sedimentation and the Distribution of Coastal Vegetation Communities along Environmental Gradients

Creator:: Lemein, Todd
Abstract:: Coastal marsh vegetation is an important component in maintaining marsh stability that is threatened by changes in sedimentation, sea level rise, natural and anthropogenic disturbances, and competition from invasive species. Vegetation has been demonstrated to reduce wave energy, increase sedimentation, and decrease erosion in tidal environments under a range of...

Exploring the Impacts of Climate and Management on Coastal Community Vulnerability through Alternative Future Scenarios

Creator:: Mills, Alexis K.
Abstract:: Coastal communities throughout the U.S. Pacific Northwest face heightened risk due to sea level rise and increasing storminess resulting in coastal flooding and erosion hazards. Incorporating uncertainty with respect to both climate change and policy decisions is essential to project the evolving probability of coastal inundation and erosion, and the...

Extreme Wave Runup and Runup Variability on Beaches

Creator:: Li, Chuan
Abstract:: Wave runup is an important physical process that affects nearshore sediment transport, coastal erosion, and flooding. Large and unexpected runup events can also be dangerous to beach goers. Extreme runup statistics are essential parameters used in engineering design of marine structures and in coastal management. Although the study of runup...

Examining Wave Attenuation Rates and Subsurface Pore Pressures Across Three Marsh Restoration Sill Structures on a Sandy Bed

Creator:: Converse, Jordan D.
Abstract:: With rising sea levels and more frequent exposure to extreme storms, coastlines worldwide are vulnerable to increased erosion and loss of natural marsh lands. In an effort to lessen these impacts, there is a growing practice of adapting hard or “gray” coastline protection techniques to more nature-based features that promote...
