| Bedload and nearbed transport of coarse (>1mm) detritus particles were investigated in a tidal creek of a salt marsh in the Westerschelde estuary (south-west Netherlands). Using a fyke net positioned on the creek bottom, hourly transport through the creek was measured during 14 flood-ebb cycles in 1990 and 1991. Transport was bi-directional with flood imports varying between 32 and 2601 g dry weight (DW), and ebb exports varying between 0 and 4737 g DW. In nine of 14 tidal cycles, the creek was functioning as a net exporting system. The material that was exported with the ebb consisted mainly of macrophyte material. The annual loss of coarse organic matter by bedload plus nearbed transport through the creek was estimated to be less than 0-2% of the... |

| The utilization of an estuarine brackish marsh in the Westerschelde estuary (southwest Netherlands) by fish and crustaceans visiting the intertidal creeks at rising tides was investigated over an 18 mo period. Samples were collected every month over a tidal cycle. A stow net passively fished the nekton migrating in and out of the marsh habitat. Simultaneous measurements of current speed and waterheight allowed for quantification of the catches. Multivariate clustering and ordination techniques were applied to assess temporal changes in the nekton assemblage. A total of 68 fish and crustacean species were caught but only 38 were regular visitors of the marsh creek. The marsh nekton community proved to have a very stable character. Only 40% of the observed... |
