Projections of high rates of sea level rise have stimulated proposals for adaptation strategies with increasingly high nourishment volumes along sandy beaches. An underlying assumption is that coastal profiles respond rapidly to nourishments by redistributing sediments towards a (new) equilibrium shape. However, this perception may not be...

In future decades, coasts will be exposed to increasing risks because of climate change and sea level rise, which poses an increased threat of coastal inundation, erosion and ecosystem loss. The natural variability of coasts can make it difficult to identify these impacts. Most beaches worldwide show evidence of recent erosion. Sea level rise is...

Recently, mega feeder nourishments have been proposed as a new strategy to nourish sediment-starving beaches. This strategy involves the placement of a large, concentrated sediment volume at a single location along the coast. Wind, waves and currents act as the natural agents to spread the sediment alongshore over the course of years to decades....

In this paper, a new approach to model wave‐driven, cross‐shore shoreline change incorporating multiple timescales is introduced. As a base, we use the equilibrium shoreline prediction model ShoreFor that accounts for a single timescale only. High‐resolution shoreline data collected at three distinctly different study sites is used to train...

Intertidal bars are naturally occurring morphological features along the waterline of sandy beaches. Present quantitative knowledge on intertidal bar behavior is limited, due to the scarcity of data resources and the limitations of traditional survey techniques. To investigate and quantify the cross-shore morphologic behavior of intertidal...

The beach recovery process determines the resilience of a sandy coast and is an important aspect of the coastal safety. Sediment stored underwater due to storms is transported onshore by the migration of subtidal and intertidal bars under mild wave conditions. The intertidal zone is an im-portant interface, connecting the marine and aeolian zone...

We investigated whether cross-shore distributions of coastal phytoplankton to the surf zone are controlled by hydrodynamics and their biological characteristics. Data from a rip-channeled beach indicate that concentrations of phytoplankton are higher in the surf zone than offshore. To examine how phytoplankton is transported toward the shore,...

The Sand Engine is a 21.5 million m<sup>3</sup> experimental mega-nourishment project that was built in 2011 along the Dutch coast. This intervention created a discontinuity in the previous straight sandy coastline, altering the local hydrodynamics in a region that is influenced by the buoyant plume generated by the Rhine River. This work...

We present a new mechanism for cross-shore transport of fine sediment from the nearshore to the inner shelf resulting from the onshore propagation of river plume fronts. Onshore frontal propagation is observed in moorings and radar images, which show that fronts penetrate onshore through the nearshore and surf zone, almost to the waterline....

The Rhine ROFI ( region of freshwater influence) is a dynamic area where various processes and timescales come together. Research has shown that stratification caused by the freshwater outflow of the Rhine alters the tidal currents in front of the Dutch coast. In the case of the Netherlands the tide behaves like a kelvin wave, which causes...

River plumes, also regions of freshwater influence , are important features to understand because of their impact on the current structure, stratification and the transport of fine sediments, nutrients and contaminants. One important river plume is the Rhine ROFI. Prior studies have sought to understand far-field dynamics where cross-shore...

Larvae of many intertidal species develop offshore and must cross the surf zone to complete their onshore migration to adult habitats. Depending on hydrodynamics, the surf zone may limit this migration, especially on reflective rocky shores. As a logistically tractable analog of a rocky shore environment, we carried out a comprehensive...

The cross-shore sediment transport is of great importance in the coastal water since it may lead to significant change of coastal profile. Many researches have proved that the sediment transport is proportional to velocity moments. In this study, the velocity moments under wave action in the perpendicular direction to the coastline are studied...

The longshore sediment transport (it will be referred also as LST) is a core issue in the field of coastal engineering. It is among the most important nearshore processes that control the coastal morphology, and determines in large part whether shores erode, accrete, or remain stable. Consequently, it is important to be able to calculate the LST...

A new approach in coastal maintenance is the application of a large scale nourishment as natural feeder of the coast. The Sand Motor constructed near Kijkduin on the Holland Coast is a pilot project of this new nourishment strategy. The objective of this research is to contribute to a better understanding of the sediment transport processes at...

Longshore sediment transport (LST) is one of the main drivers of beach morphology. Bulk LST formulas are routinely used in coastal management/engineering studies to assess LST rates and gradients. However, there is still great uncertainty in LST estimation with these bulk formulas. This uncertainty may have two sources: 1) experimental errors in...

The scientific foundation to maintain the Holland Coast shoreward of the -20m depth contour is limited. It is assumed that profile perturbations shoreward of the -20m depth contour influence the coast within a time scale of 50 to 200 years. Hence, seaward of -20m NAP dredging companies are allowed to dredge sand. The dredged material is amongst...

As a good rule of thumb, one-line models have been in use for a wide range of coastal projects for the past 30 years to predict the beach morphological change and make the appropriate shoreline management plans. Though applied to many coastal sites with certain success, these models are still under further development so as to achieve better...

Holland is a densely populated country with an important coastal zone that comprises most of the Dutch population. The dunes, the beach and the shoreface are a natural sandy protection for the Dutch coast. Natural processes, such as waves, winds and tides, coupled with human activity, may lead to shoreline erosion. Gradual recession of the coast...
