Modeling bed evolution using weakly coupled phase-resolving wave model and wave-averaged sediment transport model [PDF]

, 2016
In this paper, we propose a model for the simulation of the bed evolution dynamics in coastal regions characterized by articulated morphologies.

An analytical model for bore-driven run-up [PDF]

, 2008
We use a hodograph transformation and a boundary integral method to derive a new analytical solution to the shallow-water equations describing bore-generated run-up on a plane beach.

Vertical structure of near-bed cross-shore flow velocities in the swash zone of a dissipative beach [PDF]

, 2015
Cross-shore velocity profiles are measured at 0.001m vertical resolution and at 100Hz over the lower 0.02-0.07m of the water column in the mid swash zone on a dissipative, macrotidal beach.

The effects of tides on swash statistics on an intermediate beach [PDF]

, 2011
Swash hydrodynamics were investigated on an intermediate beach using runup data obtained from video images. Under mild, near-constant, offshore wave conditions, the presence of a sandbar and the tidally controlled water depth over its crest determined ...

Direct Measurements of Bed Shear Stress under Swash Flows on Steep Laboratory Slopes at Medium to Prototype Scales

Journal of Marine Science and Engineering, 2019
Robust measurements of bed shear stress under wave runup flows are necessary to inform beachface sediment transport modelling. In this study, direct measurements of swash zone bed shear stress were obtained in medium and prototype-scale laboratory ...

Lidar Observations of the Swash Zone of a Low-Tide Terraced Tropical Beach under Variable Wave Conditions: The Nha Trang (Vietnam) COASTVAR Experiment

Journal of Marine Science and Engineering, 2020
A field experiment was conducted at a tropical microtidal intermediate sandy beach with a low tide terrace (Nha Trang, Vietnam) to investigate the short-term swash-zone hydrodynamics and morphodynamics under variable wave conditions.

Large scale experiments on beach evolution induced by bichromatic wave groups with varying group period [PDF]

, 2014
New large scale experimental data have been presented showing the wave group influence on beach morphodynamics at the surf and swash zones. Bichromatic wave conditions were generated varying the modulation bandwidth but keeping the wave energetic content
