A new alternative to saving our beaches from local sea-level rise: the sand engine.A boldly innovative soft engineering intervention, comprising an unprecedented 21.5 Mm3 nourishment known as Sand Engine, has recently been implemented in Netherlands. The Engine is a pilot project test efficacy of mega-nourishments counter...
The retention of floating matter within the surf zone on a rip‐channeled beach is examined with combination detailed field observations obtained during Rip Current Experiment and three‐dimensional (3‐D) wave flow model. acoustic Doppler current profiler–observed hourly vertical cross‐shore velocity structure variability over period 3 days normally incident swell well reproduced by computations, although strong attenuation subsurface rip velocities at most offshore location outside in 4 m...
Abstract Wave‐supported gravity flows (WSGFs) generate rates of sediment flux far exceeding other cross‐shelf transport processes, contributing disproportionately to shelf morphology and net fluxes in many regions worldwide. However, the conditions deemed necessary for formation WSGF limit them a narrow set conditions; they have been observed exclusively where seabed consists very fine‐grained typically co‐occur with nearby river flood events. Here we document occurrence event on...
Abstract We present a new mechanism for cross‐shore transport of fine sediment from the nearshore to inner shelf resulting onshore propagation river plume fronts. Onshore frontal is observed in moorings and radar images, which show that fronts penetrate through surf zone, almost waterline. During passage two‐layer counterrotating velocity field characteristic tidal straining immediately set up, generating net offshore flow beneath plume. The seaward at depth carries with it high suspended...
[1] Observations of the spatially dependent velocity field over movable bed forms subjected to slightly skewed and asymmetric regular wave forcing were collected. The dynamics between ripple elements is dominated by coherent vortices, characterized swirling strength, evidenced in temporal spectral characterization. Within boundary layer, energy second harmonic (3f0) amplified at slopes consistent with location expected strongest pressure gradients. First-moment second-moment statistics used...

To study onshore bar migration and the accompanying intra-wave sediment transport a wave flume experiment was conducted. The had rigid bottom with single profile. focus of to measure hydrodynamics in boundary layer. results show that skewness stress is not only related but also asymmetry.
The cause of sediment suspension events during flow reversal under waves in the nearshore is not well understood. Vortex tubes and horizontal pressure gradients have been suggested to be events. A medium sized wave flume experiment has conducted give insight hydrodynamics bottom boundary layer over a fixed single-barred profile. Flow measurements were made with PIV swirling strength velocity fields analyzed. Around vortex identified. had similar size as vortices generated by shedding rippled...

This thesis is about the hydrodynamic processes that occur when a nearshore sandbar migrates towards shore driven by waves. These are relevant because process-based morphological models have difficulty simulating coastal accretion events in contrast to erosion events. Simulating important for engineering purposes, example, optimize shoreface nourishment conservation of beach and dunes Netherlands. During onshore migration, sediment dominantly transported at bed where orbital wave motion...

The South-Holland coast of the Netherlands undergoes influence Rhine river plume released from Rotterdam waterways. An experiment, STRAINS, was conducted to study impact fresh water on nearshore hydrodynamics and sand transport.
