Grain size and gradation effects on sediment transport under sheet-flow conditions, data analysis

This study consists of three sections: - experiments on sand transport in oscillatory sheet flow with two sands (D50 = 0.21 and 0.32 mm) - verification of three existing sediment transport models - extension of these models to include the gradation of the sediment The experiments are performed in the Large Oscillating Water Tunnel (see also data...

Modellering van het sedimenttransport over de Plaat van Ossenisse in de Westerschelde

Het bepalen van het sedimenttransport over de Plaat van Ossenisse is van belang om inzicht te krijgen in de processen die een rol spelen bij de aanzanding van de Drempel van Hansweert. Deze drempelligt in de vaargeul ten oosten van de Plaat van Ossenisse. Er is reeds een studie verricht naar drempelvormende mechanismen, maar deze hebben...

Rip currents, morphodynamic simulations

Rip currents are narrow and intense, offshore directed flows in the nearshore zone. A rip current is able to transport a considerable amount of water and sediment seaward and may dominate the morphological exchange between surfzone and the offshore. Rip currents are often located nearby lateral boundaries that obstruct the longshore current, but...
