Abstract: Estuarine fine sediment transport is governed by a wide range of hydrological, chemical and biological parameters including baroclinic circulation, tidal pumping, resuspension, deposition, flocculation and biomass changes associated with salinity, temperature and water quality distributions. A field survey conducted in 1985 over a 30 km reach of the lower Weser Estuary showed that erosion and deposition play a dominant role in the short term turbidity concentrations within the turbidity maximum region. This is a surprising result when one considers that turbidity is generally attributed to 'suspended sediment' of particles < 100 μm.
