“…These latter low values are caused by the large dimensions of the tidal channels that fed the former Zuiderzee and the geologically young age of this part of the Wadden Sea. The construction of the closure dam 'Afsluitdijk' in 1932 separated the shallow Zuiderzee from the active basins, rendering these tidal channels too large for their new function (Elias et al, 2003;Elias & Van der Spek, 2006).…”

“…1). The reduced basin dimensions after the closures of the Zuiderzee and Lauwerszee, in combination with dykes protecting the remainder of the mainland, formed the Wadden Sea as we know it today (Biegel & Hoekstra, 1995;Oost, 1995;Elias & Van der Spek, 2006).…”

“…5 and 6). A major part of the eroded volume (130 million m 3 ) was delivered by the erosion of the ebb-tidal delta margin, and scouring of large tidal channels in a southward direction (Elias et al, 2003;Elias & Van der Spek, 2006). The stable position of the inlet channel is due to Helderse Zeewering (a stone seawall protecting the tip of North Holland).…”

“…The erosion and coastline retreat result from the presence of the large nearshore tidal channels. These channels capture a large amount of the littoral drift, limiting sediment bypassing and beach recovery (Elias & Van der Spek, 2006). Maintenance of the stretches of coast along Texel Inlet belongs to the most intensive of the entire Dutch coastal system (Roelse, 2002;Cleveringa et al, 2004;Hoogervoorst, 2005).…”

The availability of nearly 100 years of bathymetric measurements allows the analysis of the morphodynamic evolution of the Dutch Wadden Sea under rising sea level and increasing human constraint. The historically observed roll-over mechanisms of landward barrier and coastline retreat cannot be sustained naturally due to numerous erosion control measures that have fixed the tidal basin and barrier dimensions. Nevertheless, the large continuous sedimentation in the tidal basins (nearly 600 million m 3 ), the retained inlets and the similar channel-shoal characteristics of the basins during the observation period indicate that the Wadden Sea is resilient to anthropogenic influence, and can import sediment volumes even larger than those needed to compensate the present rate of sea-level rise. The largest sedimentation occurs in the Western Wadden Sea, where the influence of human intervention is dominant. The large infilling rates in closed-off channels, and along the basin shoreline, rather than a gradual increase in channel flat heights, render it likely that this sedimentation is primarily a response to the closure of the Zuiderzee and not an adaptation to sea-level rise. Most of the sediments were supplied by the ebb-tidal deltas. It is, however, unlikely that the sediment volume needed to reach a new equilibrium morphology in the Western Wadden Sea can be delivered by the remaining ebb-tidal deltas alone.

“…Inlets probably represent one of the most challenging environments for the evaluation of sediment transport quantities related to the acting physical forces (Komar, 1996), and they have been the subject of a number of process-based models that provide valuable information on governing flow and sediment transport patterns (Wang et al, 1995;Cayocca, 2001;Ranasinghe and Pattiaratchi, 2003;Van Leeuwen et al, 2003;Siegle et al, 2004Siegle et al, , 2007Elias and Spek, 2006;Van der Vegt et al, 2006;Elias and Hansen, 2013). However, most of the previous studies have been focused on what might be called the macro-scale morphology of ebb shoals and channels, describing the ebb-tidal delta in terms of a small number of sediment lobes and channels.…”

Wind‐driven modifications to the residual circulation in an ebb‐tidal delta: Arcachon Lagoon, Southwestern France

A combination of observations and analytical solutions was used to determine the modifications caused by wind forcing on the residual or nontidal circulation in an ebb-tidal delta. Observations were obtained in the lower Arcachon Lagoon, southwestern France. The basic nontidal circulation was established with acoustic Doppler current profilers (ADCPs) that were (i) moored in the delta's two deepest channels, and (ii) towed along a cross-lagoon transect. The bathymetry of the lower lagoon, or ebb-tidal delta, featured two channels: North Pass (>9 m) and South Pass (>20 m). The basic nontidal circulation consisted of mostly inflow with weak surface outflow in the South Pass, and laterally sheared bidirectional flow, dominated by outflow, in the North Pass. Analytical solutions and comparison of observed dynamical terms suggested that, in addition to the conventionally accepted influence of tidal nonlinearities, density gradients contributed to the basic nontidal circulation in the lagoon. Observations also indicated that wind forcing altered the basic circulation by driving simultaneous upwind flows in both passes. This response was supported by an analytical solution to wind-driven flows over the bathymetry of the transect sampled. The response to seaward winds was to enhance inflow in South Pass and reduce outflow in North Pass. Landward winds caused diminished inflow in South Pass and increased outflow in North Pass.
