    Rising sea levels and the increase of shoreline wave energy at American Samoa

    American Samoa is experiencing rapid relative sea level rise due to increases in global sea level and significant post-2009 earthquake land subsidence, endangering homes and critical infrastructure. Wave and w...

    Southern California winter precipitation variability reflected in 100-year ocean salinity record

    Rainfall in southern California is highly variable, with some fluctuations explainable by climate patterns. Resulting runoff and heightened streamflow from rain events introduces freshwater plumes into the coa...

    Wave setup at the Minamitorishima tide gauge

    A tide gauge situated on the western shore of Minamitorishima, a small atoll in the western Pacific, has measured sea levels significantly impacted by wave setup. Evidence for this rests with (a) strong correl...

    An early warning system for wave-driven coastal flooding at Imperial Beach, CA

    Waves overtop berms and seawalls along the shoreline of Imperial Beach (IB), CA when energetic winter swell and high tide coincide. These intermittent, few-hour long events flood low-lying areas and pose a gro...

    Rapid increases and extreme months in projections of United States high-tide flooding

    Coastal locations around the United States, particularly along the Atlantic coast, are experiencing recurrent flooding at high tide. Continued sea-level rise (SLR) will exacerbate the issue where present, and ...

    Predicting site-specific storm wave run-up

    Storm wave run-up causes beach erosion, wave overtop**, and street flooding. Extreme runup estimates may be improved, relative to predictions from general empirical formulae with default parameter values, by...

    Forcing Factors Affecting Sea Level Changes at the Coast

    We review the characteristics of sea level variability at the coast focussing on how it differs from the variability in the nearby deep ocean. Sea level variability occurs on all timescales, with processes at ...

    Inundation of a low-lying urban atoll island: Majuro, Marshall Islands

    Majuro is a low-lying island perched on a coral atoll in the central Pacific Ocean and is home to nearly 28,000 people. Considered highly vulnerable to the impacts of marine inundation, Majuro is expected to ...
