Coupling Methodology for Studying the Far Field Effects of Wave Energy Converter Arrays over a Varying Bathymetry

Energies, 2018
For renewable wave energy to operate at grid scale, large arrays of Wave Energy Converters (WECs) need to be deployed in the ocean. Due to the hydrodynamic interactions between the individual WECs of an array, the overall power absorption and surrounding

Influence of the Initial Beach Profile on the Sediment Transport Processes During Post‐Storm Onshore Bar Migration

Journal of Geophysical Research: Oceans, Volume 128, Issue 4, April 2023., 2023
Abstract Onshore bar migration is a characteristic bar behavior during post‐storm beach recovery. The present large‐scale experiments, feature bichromatic wave groups over an initially steep (1:15), fully‐evolving beach. The same accretive wave condition is applied on two different post‐storm beach profiles featuring outer and inner bars.

Near‐Bed Sediment Transport Processes During Onshore Bar Migration in Large‐Scale Experiments: Comparison With Offshore Bar Migration

Journal of Geophysical Research: Oceans, Volume 128, Issue 3, March 2023., 2023
Abstract Detailed information on nearshore sediment transport processes during onshore bar migration were obtained from large‐scale laboratory experiments with bichromatic wave groups on a relatively steep initial beach slope (1:15). Detailed measurements of velocity and sand concentration near the bed from shoaling up to the outer breaking zone ...

New Perspectives for Nonlinear Depth‐Inversion of the Nearshore Using Boussinesq Theory

Geophysical Research Letters, Volume 50, Issue 2, 28 January 2023., 2023
Abstract Accurately mapping the evolving bathymetry under energetic wave breaking is challenging, yet critical for improving our understanding of sandy beach morphodynamics. Though remote sensing is one of the most promising opportunities for reaching this goal, existing depth‐inversion algorithms using linear approaches face major theoretical and/or ...

Near‐Bed Sediment Transport During Offshore Bar Migration in Large‐Scale Experiments

Journal of Geophysical Research: Oceans, Volume 127, Issue 5, May 2022., 2022
Abstract This study presents novel insights into hydrodynamics and sediment fluxes in large‐scale laboratory experiments with bichromatic wave groups on a relatively steep initial beach slope (1:15). An Acoustic Concentration and Velocity Profiler provided detailed information of velocity and sand concentration near the bed from shoaling up to the ...

A Link Between Plant Stress and Hydrodynamics? Indications From a Freshwater Macrophyte

Water Resources Research, Volume 57, Issue 9, September 2021., 2021
Abstract Live plants are increasingly used in hydraulic laboratories to investigate flow‐vegetation interactions. In such experiments, they are often exposed to stressful handling and storage that can cause strong physiological responses and modifications in plant biomechanics.

A Convolution Method to Assess Subgrid‐Scale Interactions Between Flow and Patchy Vegetation in Biogeomorphic Models

Journal of Advances in Modeling Earth Systems, Volume 13, Issue 2, February 2021., 2021
Abstract Interactions between water flow and patchy vegetation are governing the functioning of many ecosystems. Yet, numerical models that simulate those interactions explicitly at the submeter patch scale to predict geomorphological and ecological consequences at the landscape scale (order of km2) are still very computationally demanding.
