The KdV and Whitham limit for a spatially periodic Boussinesq model
… für ein räumlich periodisches Boussinesq-Modell. Wir zeigen Abschätzungen der Differenz zwischen der KdV- beziehungsweise der Whitham-Approximation und echten Lösungen des ursprünglichen Modells, welche garantieren, dass diese Amplituden-Gleichungen korrekte Vorhersagen über die …

Wave breaking onset and dissipation in a fully non-linear, staggered grid Boussinesq model
… weakly-nonlinear (WNL) and fully-nonlinear (FNL) Boussinesq-type (BTE) models. We consider two primary questions: • 1. Is the FNL model capable of accurately reproducing shoaling behavior and esti- mates of parameters needed to describe the onset of breaking? • 2. How can the description of …

Observations and modeling of wave-acceleration-induced sediment transport in the surfzone
… but are not understood well. Here, a new model that accounts for accelerations of wave-orbital velocities predicts onshore sandbar migration observed on an ocean beach. In both the observations and the model, the location of the maximum acceleration-induced transport moves shoreward with …

Impact of Patchy Vegetation on Wave and Runup Dynamics
… Dalehite Cove, Galveston Bay, TX, results from a Boussinesq model (COULWAVE) showed patchy vegetation reduced up to 75% mean shoreward current in the mound-channel wetland systems. These vegetation patches also reduced the primary circulation around mounds, with a power-form relation between …

Flow and stability studies in porous media based on some non-Darcian models.
… problems in porous media using some non-Darcian models. It is divided into three parts, which are essentially independent of each other. The first part deals with the theoretical study related with the solution of the Brinkman equation. An exact Cartesian-tensor form solution of the Brinkman …

Field and numerical investigations of wave transformation and inundation on atoll islands
… unstudied atoll. Subsequently, a fully nonlinear Boussinesq model was used to simulate wave processes on Fatato and other reefs with variable morphology to evaluate the impact of sea level rise (SLR) on shoreline wave energy, runup and inundation within atoll environments. Field data from Fatato …

Gap winds in a fjord : Howe Sound, British Columbia
… combination of observations and several types of models. Observations of winds in Howe Sound showed that gap wind strength varied considerably along the channel, across the channel and vertically. Generally, winds increase down the channel, are strongest along the eastern side, and are below 1000 …
