  • 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...

  • Field validation of a nearshore circulation model for alongshore-nonuniform flows

    Creator:
    Wilson, Gregory W.
    Abstract:
    We investigate, theoretically and experimentally, the problem of modeling depth-integrated (2DH) surf zone circulation on an alongshore-nonuniform natural beach, with waves approaching from an arbitrary angle. An approximate theoretical model is developed, which captures the important effect of advection in the alongshore dynamics, and shows that a nondimensional parameter Re[subscript]s...
