Numerical modelling of hydrodynamics of permeable pile groins using SWASH

This paper focuses on a specific form of groins, Permeable Pile Groins (PPGs), consisting of a single or double rows of wooden piles. With only few experiments and simulations available to study the hydraulic functioning of PPGs, the correlation between the effectiveness and the characteristics of the groin system has yet to be fully understood....

Laboratory validation of SWASH longshore current modelling

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. While wave current interaction is...

Modelling of bed sediment composition changes at the lower shoreface of the Sand Motor

Large perturbations in the coastline, such as the 'Sand Motor' nourishment (∼21 million m³) at the Holland coast, can initiate considerable spatial and temporal changes in the median grain size (D₅₀) of the sea bed on the lower shoreface. The relevance of hydrodynamic conditions for the development of the heterogeneity...
