Effects of tide range alterations on salt marsh sediments in the Eastern Scheldt, S. W. Netherlandsds. In 1986 the mean high tide level was reduced by almost one metre. This excluded the greater part of the medium-high marshes almost completely from tidal flooding..The absence of tidal flooding in the summer of 1986, combined with a net precipitation deficit, increased the bulk density of the sed

This doubling of the phytoplankton and the microphytobenthos production has been ascribed to the eutrophication of that area: mean annual phosphate concentrations have increased, whereas the nitrogen concentrations have not. Analysis of the available production data indicates a more
