| The intertidal fauna of a Belgian sandy beach was sampled on an hourly basis with a hand-pushed sledge to study circadiel patterns in species composition. Four assemblages could be distinguished with classification and ordination techniques. A first division separated the samples taken during daytime from the night samples. Both assemblages were subsequently divided into an ebbtide and a floodtide situation. Light intensity and tidal height were the most important variables explaining the variation in the Canonical Correspondence Analysis. |

| In many cases maintenance dredging in harbors and access channels could be much cheaper and easier if the deposited mud could be pumped using fixed equipment. Therefore the feasibility of pumping fluid mud was examined. It is found that homogeneous mud can be pumped efficiently up to densities of 1150 kgm<sup>-3</sup> (for the Zeebrugge (Belgium) mud). For higher densities the influence radius of the pumps becomes very small. A 1-D model can be used to determine the static equilibrium slope and the equilibrium profile of the mud-water interface. Layered mud deposits are more difficult to remove by pumping, since after each pumping cycle a layer of mud remains. As a consequence, layered mud deposits must be homogenized before pumping. This can... |
