Abstract
    A reconnaissance study on sediment transport pathways has been carried out in the Broers Bank - Westdiep coastal system with the aim of physically characterising the habitat structure of shallow marine ecosystems. Sediment transport modelling on the basis of current meter data and sedimentological information revealed that the tidal currents have a high potential for sediment movement. Due to a high sediment influx and the ability to erode older Tertiary clay layers, deposition of fine-grained material is high; hence the development of bedforms is often inhibited. Still, medium to large dunes occur where medium sands are predominant; hence where the bed shear stress is highest. Due to the shallowness of the area, the dynamics of the dunes will be largely dependant on the prevailing hydro-meteorological conditions.
