Modelling of sediment movement in the surf and swash zones
Acta Oceanologica Sinica, 2015Under the action of marine currents, non-cohesive sediments evolve by bed-load, by saltation or suspension depending on their granulometry. Several authors have considered that the movement of sediment is bidimensional and modelized the effects of swell by a constant velocitynear the seabed.

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.

Advances in numerical modelling of swash zone dynamics
Coastal Engineering, 2016We present a comprehensive and critical review of work on the numerical modelling of swash zone processes between 2005 and 2015. A wide range of numerical models has been employed for the study of this region and, hence, only phase-resolving approaches (i.e., depth-averaged and depth-resolving models) are analyzed. The current advances in the modelling

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

Modeling sediment transport in the swash zone: A review
Ocean Engineering, 2009A critical review of conceptual and mathematical models developed in recent decades on sediment transport in the swash zone is presented. Numerous studies of the hydrodynamics and sediment transport in the swash zone in recent years have pointed out the importance of swash processes in terms of science advancement and practical applications. Evidently,

Modelling and control of swash-plate dynamics
2008There are many new examples of applications of hydrostatic transmissions in the mobile scope. Beside the efficiency, the control ability and the fast response of the hydrostatic transmission are very important in modern applications. In this regard, a DC servomotor can be applied as an actuator of the variable displacement mechanism of smaller ...

Swash Zone Dynamics: Modeling and Data Analysis
2003Abstract : The goals of the work are to develop improved predictive capability for non-linear time-dependent dynamics in the swash zone. The work involves numerical computations, comparison with field and laboratory results, and theoretical analysis. The focus of the project is to quantify net onshore-offshore swash zone properties from Computational ...

Measurement and modelling of hydrodynamics at the surf-swash boundary
2011Swash zone boundary conditions are investigated using field observations of the inner surf zone and the swash zone for a range of micro-tidal, predominantly swell-dominated, sandy beaches. The boundary conditions are characterized in terms of a terminal bore height and the asymmetry between uprush and backwash flows.

Lagrangian modelling of suspended sediment in the swash zone
2009A numerical model is presented to simulate transport and beach morphology in the swash zone. The model resolves the non-linear shallow water equations in an Eulerian framework and then solves the advection-diffusion equation for turbulence and suspended sediment in a Lagrangian framework.
