“…The tide behaves as a Kelvin wave propagating from South to North along the Dutch coast so that the peak of flood currents coincides with HW so does the peak of ebb currents with LW. The orientation of tidal ellipses generally follows the isobaths (Van der Giessen et al, 1990). The semidiurnal band, which is dominated by the M 2 constituent, holds about 90%…”

“…Previous studies have described a pronounced baroclinic cross-shore circulation along the Dutch coast, in regions where the water column is stratified (Van der Giessen et al, 1990;Visser et al, 1994;De Boer et al, 2009). The cross-shore baroclinic pressure gradient is the main driver of the cross-shore exchange currents controlling the orientation of the cross-shore circulation which switches every low water (LW) and high water (HW), owing to the effects of the cross-shore tidal straining (Souza & James, 1996).…”

The Sand Engine is a 21.5 million m 3 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 investigates the response of the cross-shore stratified tidal flow to the coastal protrusion created by the Sand Engine emplacement by using a 13 hour velocity and density survey. Observations document the development of strong baroclinic-induced cross-shore exchange currents dictated by the intrusion of the river plume fronts as well as the classic tidal straining which are found to extend further into the nearshore (from 12 to 6 m depth), otherwise believed to be a mixed zone.

The circulation and water-mass structure in the Gulf of Augusta are described with respect to their influence on the deep-chlorophyll maximum (DCM). The Messina Mixed Water (MMW) mass is created in the Strait of Messina and transported southward along the shelf break. The MMW is defined by a lower salinity and higher nutrient values, and it defines the pynocline and DCM environment. It is demonstrated that variations in the direction of this current generate convergences or divergences over the shelf and result in a complex circulation. For the case of an offshelf veering of the current, a divergence is generated over the shelf that creates a circulation pattern in which the advection of MMW onshore, and therefore biological production, is favoured. The shear in the pycnocline also has an influence on the biology such that particles sinking through the pycnocline are exposed to changes in horizontal speed and direction.
