Albers, T., von Lieberman, N.. Morphologische Veränderungen von Wattflächen am Beispiel des Neufelder Sandes in der Elbmündung. In: Gönnert, G., Pflüger, B., Bremer, J.-A. (eds.).

The areas of the wadden sea at the German North Sea coast are affected by intense morphodynamics. Especially in the estuaries a change of sedimentation and erosion occurs on different time scales. The Institute of River and Coastal Engineering at the Hamburg University of Technology (TUHH) runs extensive measurements to collect data in the area “Neufelder Watt” at the mouth of the Elbe estuary. Since July 2006 water levels, flow velocities and flow directions have been recorded continuously. Also the concentration of suspended sediments has been measured and recorded in high resolution within a cross section of the tidal creek “Neufelder Rinne”. Furthermore, waves have been recorded and measured at various locations. In frequent intervals the bathymetry is determined by a multi-beam echo sounder attached to the research vessel, provided by the institute. On shorter time scales relocations of the Neufelder Rinne can be observed. To assess these changes in the context of the development of the whole area under investigation, the sediment balances over the last decades were analysed. A goal of the research project is to improve the understanding of morphodynamic processes on tidal flats and to point out relations between tidal currents, wind and wave induced currents and the sediment transport. The results flow into the creation of a module to model the sediment transport in shallow water areas of the wadden sea and therefore contribute to an improved sediment management of estuaries.
