  • 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...

  • Data assimilation for prediction of shallow water flows with uncertain bathymetry

    Creator:
    Wilson, Gregory W.
    Abstract:
    A new method is introduced for incorporating bathymetric uncertainty into predictions of nearshore and river flows (i.e., unstratified flows primarily forced by pressure and radiation stress gradients). The method involves the use of the ensemble Kalman filter (EnKF) as a parameter estimation scheme, where the parameter to be estimated is...

  • Optimizing map projection selection for world maps and web maps

    Creator:
    Šavrič, Bojan
    Abstract:
    The selection process for map projections is a mystery to many mapmakers and GIS users. Map projections ought to be selected based on the map’s geographic extent and the required distortion properties, with the goal of minimizing the distortion of the mapped area. Despite some available selection guidelines, the selection...

  • 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...
