On wave breaking for Boussinesq-type models

M Kazolea, M Ricchiuto - Ocean Modelling, 2018 - Elsevier
We consider the issue of wave breaking closure for Boussinesq type models, and attempt at
providing some more understanding of the sensitivity of some closure approaches to the …

High order methods for CFD

R Abgrall, M Ricchiuto - Encyclopedia of Computational Mechanics, 2017 - inria.hal.science
We provide a review of high order methods for CFD. Besides recalling some classical
methods, we show a framework allowing on one hand to see and work with these methods …

Modeling shallow water waves

D Lannes - Nonlinearity, 2020 - iopscience.iop.org
We review here the derivation of many of the most important models that appear in the
literature (mainly in coastal oceanography) for the description of waves in shallow water. We …

A new model of shoaling and breaking waves: one-dimensional solitary wave on a mild sloping beach

M Kazakova, GL Richard - Journal of Fluid Mechanics, 2019 - cambridge.org
We present a new approach to model coastal waves in the shoaling and surf zones. The
model can be described as a depth-averaged large-eddy simulation model with a cutoff in …

An operator-splitting approach with a hybrid finite volume/finite difference scheme for extended Boussinesq models

R Lteif - Applied Numerical Mathematics, 2024 - Elsevier
In this paper, we present a hybrid numerical scheme combining finite volume and finite
difference methods (FV/FD), for solving two extended Boussinesq-type (BT) models. We …

The shoreline problem for the one-dimensional shallow water and Green-Naghdi equations

D Lannes, G Métivier - Journal de l'École polytechnique …, 2018 - numdam.org

shallow water equations, more precise by one order of approximation. These equations are …

Implementation and evaluation of breaking detection criteria for a hybrid boussinesq model

P Bacigaluppi, M Ricchiuto, P Bonneton - Water waves, 2020 - Springer
The aim of the present work has been to develop a model able to represent the propagation
and transformation of waves in nearshore areas. The focus is on the phenomena of wave …

r− adaptation for Shallow Water flows: conservation, well balancedness, efficiency

L Arpaia, M Ricchiuto - Computers & Fluids, 2018 - Elsevier
We investigate the potential of the so-called “relocation” mesh adaptation in terms of
resolution and efficiency for the simulation of free surface flows in the near shore region. Our …
