Barrages et centrales électriques hydrauliques Résumé : Wave runup statistics on beaches, dunes and coastal structures are needed for coastal management and engineering designs. Spectral wave energy–action models are widely used to predict wave propagation in deep and shallow water, incorporating the effects of refraction, bed friction, breaking and wave–wave interactions. To calculate nearshore runup or overtopping, wave-by-wave or phase-resolving modelling is necessary as spectral, phase-averaged models only give the spectral evolution and wave-induced setup. Herein, unidirectional wave propagation up a uniform slope predicted by the Simulating WAves Nearshore (SWAN) model is compared with experimental data. The surface elevation time series near the breaking position is then created from the predicted nearshore spectra and input to a non-linear shallow-water equation solver to give statistical runup predictions which are also compared with experimental data. Sensitivity to the offshore position for wave input is investigated. Runup statistics are shown to be reasonably well predicted.

Simulation of caisson breakwater movement using 2-D SPH / Benedict D. Rogers in Journal of hydraulic research, Vol. 48 N° spécial (2010) 

Public ISBD [article]  in Journal of hydraulic research > Vol. 48 N° spécial (2010) . - pp. 135-141 Titre : Simulation of caisson breakwater movement using 2-D SPH Titre original : Simulation du mouvement d'un caisson de brise-lames avec SPH 2D Type de document : texte imprimé Auteurs : Benedict D.

Barrages et centrales électriques hydrauliques Résumé : Smoothed Particle Hydrodynamics (SPH) is used to simulate the movement of a caisson breakwater in the surf zone. The open-source code SPHysics is used with a Riemann solver-based formulation. The friction force between the moving caisson and the bed is modelled with a transition from static to dynamic friction force. Results are presented for two-dimensional simulations and compared with experiments for the movement of a caisson breakwater under the forcing of periodic waves. Promising agreement with experimental data is obtained for the displacement and the horizontal forces on the caisson. It is demonstrated that the peak impact forces are better captured using finer resolution and that a Riemann solver-based formulation produces a better agreement with experiment for the predicted caisson displacement than conventional SPH.
