Cross-shore graded sediment transport:Grain size and density effects

Sediment sorting processes (sorting on grain size and density) are the result of local hydrodynamic conditions. In this paper two measuring techniques are described which derive in situ time dependent and time averaged distributions of sediment sorted on grain size and density. The technique on measuring grain size of the sediment is described in more detail. The sediment distributions give information on the local hydrodynamic conditions on different time scales. Measurements from the field serve as a test case of describing the depth of closure from measurements of sediment composition.
