Abstract
    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-3 (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 be done by water jetting, air bubble mattresses or propeller mixers.
