An empirical model for infragravity swash on barred beaches

Coastal Engineering, 2013
Abstract Idealized computational simulations with the nearshore model XBeach were carried out for a series of barred beach configurations in order to quantify the impact of nearshore bars on infragravity swash. Results show that nearshore bar systems reduce infragravity swash energy at the shoreline.

Probabilistic-Deterministic Modelling of Swash Zone Morphology

Coastal Sediments '07, 2007
A 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

NUMERICAL MODELLING OF SWASH ZONE HYDRODYNAMICS

Coastal Engineering 2002, 2003
Abstract : 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 saturation: an assessment of available models

Ocean Dynamics, 2018
An 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 ...

Integral swash-zone models

Continental Shelf Research, 2006
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

Importance of the Swash Longshore Sediment Transport in Morphodynamic Models

Coastal Sediments '07, 2007
This paper discusses the effect of the longshore sediment transport in the swash zone on the evolution of the shore line. The beach evolution model presented here is based on an N-line approach including a local estimation of the sediment transport function of the local current and wave characteristics.

Swash zone boundary conditions for long-wave models

Coastal Engineering, 2005
Abstract 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.

The Motion Modeling and Simulation of the Swash-Plate Engine

Advanced Materials Research, 2012
In order to conduct a comprehensive analysis and optimization improvements of the swash-plate engine, it is necessary to analyze and discuss the motion of the swash-plate completely. Based on the motion model of the piston and the connecting rod of the engine, the motion tendencies were simulated.

Sediment Transport Numerical Modelling in the Swash Zone

Coastal Dynamics 2005, 2006
A numerical model of sediment transport in the swash zone has been recently developed. The followed approach relies on the solution of the vertical distribution of suspended sediment concentration and incorporates the horizontal advection of suspended sediment from the bore collapse and local pickup using a Lagrangian computing scheme.
