Overtopping at Vagueira sea defence using the SWASH model
Revista Recursos Hídricos, 2023A praia da Vagueira está localizada no Município de Vagos, distrito de Aveiro e é protegida por uma estrutura de defesa frontal aderente que foi requalificada em 2015, com alteamento da sua cota de coroamento para + 10 m (ZH), devido à ocorrência de inundações na zona por ela protegida. Para caracterizar o galgamento com a estrutura atual, aplicou-se o

The SWASH model for soliton splitting due to decreasing depth
AIP Conference Proceedings, 2014 A solitary wave is a nonlinear wave that travels undisturbed in shape and velocity as a result of a balance between dispersion and nonlinearity. According to the inverse scattering theory of KdV, a solitary wave will split into N-soliton due to decreasing depth. This phenomenon is simulated using the non-hydrostatic model SWASH.

Flexible Vegetation And Its Implementation In The Swash Ocean Model
Oceans, 2021This paper reports on the implementation of a flexible vegetation solver for the SWASH nearshore ocean model intent on resolving motion of highly flexible vegetative stems and the resultant influences on the flow field. Currently, vegetation in SWASH and

NUMERICAL MODELLING OF SWASH ZONE HYDRODYNAMICS
Coastal Engineering 2002, 2003Abstract : The swash zone is the area of the nearshore that is intermittently covered and uncovered by wave run-up. Since swash hydrodynamics control the evolution of beach morphology, understanding these motions is of paramount importance. Typical studies of swash zone hydrodynamics involve the deployment of several instruments to measure the swash ...

Swash zone boundary conditions for long-wave models
Coastal Engineering, 2005Abstract In this note, a description of swash zone boundary conditions for implementation in wave-resolving and wave-averaging long-wave models is given along with a discussion of the role of such conditions on the modelling of the entire surf zone hydro-morphodynamics.

Probabilistic-Deterministic Modelling of Swash Zone Morphology
Coastal Sediments '07, 2007A probabilistic‐deterministic model for swash zone sediment transport is presented and applied to predict cross‐shore beach profile change under random waves. For accretionary conditions, inclusion of a random wave approach is essential for accurate representation of berm building processes. The model provides good estimates of beach volume changes for

Laboratory validation of SWASH longshore current modelling
Coastal Engineering, 2018Abstract In this paper, the ability of the numerical phase resolving model SWASH (Simulating WAves till SHore) to hindcast wave-induced longshore currents is evaluated. Using default settings for all processes modelled, highly accurate results are found for wave heights, mean water levels and longshore currents.

Swash saturation: an assessment of available models
Ocean Dynamics, 2018An extensive previously published (Hughes et al. Mar Geol 355, 88–97, 2014) field data set representing the full range of micro-tidal beach states (reflective, intermediate and dissipative) is used to investigate swash saturation. Two models that predict the behavior of saturated swash are tested: one driven by standing waves and the other driven by ...

A broad illustration is given of integral swash zone models as a flexible and upgradable approach for formulating shoreline boundary conditions for wave-averaged circulation models. Integral models represent a framework in which various types of flow parameterizations can be fitted to give ever-improving descriptions of swash zone motions. Examples are
