“…The model used in this study is based on a Delft3D hydrodynamic and sediment transport model originally developed specifically for the mouth of the Columbia River and which has been validated for waves and currents against field data (Elias et al, 2012). World-wide case studies indicate that Delft3D is applicable to a wide range of coastal and fluvial environments including ocean, estuary and river settings (Grunnet et al, 2004;Van Maren, 2004;Elias et al, 2006;Lesser et al, 2004;Mulligan et al, 2010). The base model for the CRE has a grid resolution varying between 50 to 100 m 2 , with an average of 20 grid cells covering the main channel of the river.…”

• We modeled sedimentation patterns in three reaches in the Columbia River Estuary.• Sediment transport model is used to guide bottom sediment sample allocation.• Organic carbon levels are correlated with predicted sedimentation patterns.• Sediment contaminants are correlated with predicted sedimentation patterns.• Longitudinal contaminant trends comport to trends in resident bird and fish tissues. While previous studies have documented contaminants in fish, sediments, water, and wildlife, few specifics are known about the spatial distribution of contaminants in the Columbia River Estuary (CRE). Our study goal was to characterize sediment contaminant detections and concentrations in reaches of the CRE that were concurrently being sampled to assess contaminants in water, invertebrates, fish, and osprey (Pandion haliaetus) eggs. Our objectives were to develop a survey design based on sedimentation characteristics and then assess whether sediment grain size, total organic carbon (TOC), and contaminant concentrations and detections varied between areas with different sedimentation characteristics. We used a sediment transport model to predict sedimentation characteristics of three 16 km river reaches in the CRE. We then compartmentalized the modeled change in bed mass after a two week simulation to define sampling strata with depositional, stable, or erosional conditions. We collected and analyzed bottom sediments to assess whether substrate composition, organic matter composition, and contaminant concentrations and detections varied among strata within and between the reaches. We observed differences in grain size fractions between strata within and between reaches. We found that the fine sediment fraction was positively correlated with TOC. Contaminant concentrations were statistically different between depositional vs. erosional strata for the industrial compounds, personal care products and polycyclic aromatic hydrocarbons class (Indus-PCP-PAH). We also observed significant differences between strata in the number of detections of Indus-PCP-PAH (depositional vs. erosional; stable vs. erosional) and for the flame retardants, polychlorinated biphenyls, and pesticides class (depositional vs. erosional, depositional vs. stable). When we estimated mean contaminant concentrations by reach, we observed higher contaminant concentrations in the furthest downstream reach with a decreasing trend in the two upstream reaches. Contaminant survey designs that account for sedimentation characteristics could increase the probability that sampling is allocated to areas likely to be contaminated. a b s t r a c t a r t i c l e i n f oPublished by Elsevier B.V.

“…Using an analytical model, this circulation was explained mainly by differences in water-level amplitude between the Texel and Vlie inlets (Ridderinkhof, 1988b). However, it was later shown, by expanding the analytical model to include wind effects, that the residual circulation between the Texel and Vlie inlets is highly variable due mainly to local wind stresses (Buijsman and Ridderinkhof, 2007b (Elias et al, 2006). They found an average outflow rate of about 2300 m 3 s −1 within a tidal period.…”

Residual circulation and freshwater transport in the Dutch Wadden Sea: a numerical modelling study

Abstract. The Dutch Wadden Sea is a region of intertidal flats located between the chain of Wadden Islands and the Dutch mainland. We present numerical model results on the tidal prisms and residual flows through the tidal inlets and across one of the main watersheds. The model also provides insight into the pathways of fresh water originating from the two sluices at the Afsluitdijk (enclosure dike) through the use of passive tracers. All these results are obtained from threedimensional numerical simulations carried out with the General Estuarine Transport Model (GETM), at a horizontal resolution of 200 m and with terrain-following vertical coordinates with 30 layers. We concentrate on the years 2009-2010, for which we impose meteorological forcing, freshwater discharge, and boundary conditions for tidal forcing and storm surges. Results from the model show an excellent agreement with various observational data sets for sea surface height, temperature, salinity and transport through the Texel Inlet. The simulations show that although tides are responsible for a characteristic pattern of residual transport through the inlets, the wind imposes a large variability on its magnitude and can even invert its direction during strong southwesterly winds. Even though these events are sporadic, they play an important role in the flushing of the Dutch Wadden Sea, as they strongly diminish the flushing time of fresh water. In addition, wind can force a residual transport across the Terschelling watershed of the same order, if not larger, than through any of the main tidal inlets, despite the fact that its tidal prism is much smaller than any of those of the inlets. For the pathways of fresh water, the Terschelling watershed turns out to be more important than was previously thought, while the opposite holds for the Vlie Inlet.

“…The residual transport of suspended sediment in the Marsdiep inlet so far has only been assessed on the basis of indirect observations (Elias et al 2006;Nauw et al 2014). Employing ferry-borne acoustic Doppler current profiler (ADCP) observations, Nauw et al (2014) obtained estimates for the gross and residual fluxes of suspended sediment across the Marsdiep inlet for the period [2003][2004][2005][2006].…”

In multiple tidal-inlet systems such as the Dutch Wadden Sea, the exchange of sediments between the coastal lagoon and the adjacent sea is controlled by the combined effect of the tides, wind-driven flows, and densitydriven flows. We investigate the variability of residual (tidally averaged) fluxes of suspended sediment with the three-dimensional numerical model GETM in relation to forcing mechanisms and model parameters. strongly throughout the year, mainly due to wind variability. The net balance between import and export of material is very sensitive to model parameters. Residual fluxes are sensitive to the geographical orientation and location of the inlets, and the effect of driving mechanisms on the residual fluxes and concentrations can be organized hierarchically, with wind forcing having the largest effect on concentration levels and variability.
