Description :
In the shoreface of the German Bight an increase of depth and a related steepening of the profile has been observed over several decades. A negative influence to coastal protection is expected. Extensive evaluations of sea survey data were started to understand the underlying morphological processes. The sea survey data are evaluated with a GIS and found inaccurate for detailed morphological studies. Statistical method for an evaluation of the data quality, morphodynamics and a concept for a morphodynamic zonation of the shoreface based on statistical parameters are presented. The results achieved with a GIS and the developed evaluation methods are more accurate and extensive than with conventional methods.
