Gravel beaches and barriers form a valuable natural protection for many shorelines. The paper presents numerical modelling study of gravel barrier beach response to storm wave conditions. XBeach non-hydrostatic model was set up in 1D mode investigate volume change overwash under wide range unimodal bimodal conditions cross sections. validated against at Hurst Castle Spit, UK. is used simulate t...

A dispersive wave hydro-sediment-morphodynamic model developed by complementing the shallow water (SHSM) equations with term from Green–Naghdi is presented. numerical solution algorithm for based on second-order Strang operator splitting The partitioned into two parts, (1) SHSM and (2) correction part, which are discretized using discontinuous Galerkin finite element methods. This technique pro...

[1] A simplified model for tidal flow in a basin is presented. The model is based on the assumption of a flat water surface oscillating synchronously in the tidal basin. Under this hypothesis the depth-averaged continuity equation becomes a Poisson equation that can be easily resolved at each instant of the tidal cycle. This formulation, which is particularly valid for small, deep basins, provi...
