Extreme water levels generating flooding in estuarine and coastal environments are often driven by compound events, where many individual processes such as waves, storm surge, streamflow, and tides coincide. Despite this, extreme water levels are typically modeled in isolated open-coast or estuarine environments, potentially mischaracterizing the true risk of flooding...
Because of highly dissipative conditions and strong alongshore gradients in foreshore
beach morphology, wave run-up data collected along the central Oregon coast during
February 1996 stand in contrast to run-up data currently available in the literature. During
a single data run lasting approximately 90 min, the significant vertical run-up elevation...
This report assesses climate change impacts and associated community and ecosystem vulnerability. It was compiled by a group of Oregon State University researchers and students, outreach specialists, and coastal community members in Tillamook County, Oregon (OR). Through sustained engagement with the Tillamook County Coastal Futures Knowledge to Action Network (TCCF...
This chapter is part of Barrier Dynamics and Response to Changing Climate.
Coastal foredunes are often the “first line of defense” for backshore infrastructure from the hazards of erosion and flooding, and they are key components of coastal ecosystems. The shape and growth characteristics of coastal foredunes, typically characterized by...
Because barriers are low-lying and dynamic landforms, they are especially sensitive to changing environmental conditions. The continued existence of barriers will depend on the degree to which these landforms can maintain elevation above sea level while also migrating landward. We are increasingly learning that ecomorphodynamic interactions (i.e., interactions between morphology,...
Natural habitats have the ability to protect coastal communities against the impacts of waves and storms, yet it is unclear how different habitats complement each other to reduce those impacts. Here, we investigate the individual and combined coastal protection services supplied by live corals on reefs, seagrass meadows, and mangrove...
High-resolution beach morphology data collected along much of the U.S. West Coast are synthesized to evaluate the coastal impacts of the 2009–10 El Niño. Coastal change observations were collected as part of five beach monitoring programs that span between 5 and 13 years in duration. In California, regional wave and...
Coastal flood hazard zones and the design of coastal defenses are often devised using the maximum
recorded water level or a ‘‘design’’ event such as the 100 year return level, usually projected from
observed extremes. Despite technological advances driving more consistent instrumental records of waves
and water levels, the observational...
This project was carried out collaboratively by Oregon State University (OSU) and the Oregon Department of Geology and Mineral Industries (DOGAMI) and involved baseline observations and
modeling at the proposed wave energy conversion (WEC) array site near Reedsport, OR. In particular, observations and predictions of the wave conditions at the...
