Various paramters for analysing morphodynamics in the German Bight on the basis of a 32 years time series of interpolated bathymatries (yeasr 1982 - 2012). Parameters: - "Morphological Alteration": differences in depth between two annual topographies for different periods (1, 5, 10, 30 years periods), - "Morphological Space": maximum difference in height at each model grid point (Zmax-Zmin) for different periods (1, 5, 10, 30 years), - "Morphological Drive": Difference between the maximum and the minimum annual rate of change in the period under consideration ((dz/a)max-( dz/a)min); 1, 5, 10, 30 years). With this parameter, it is possible to make a declaration as to whether a morphological alteration constantly takes place throughout the period under consideration or extreme results have occurred: - "Count Of Datasets": amount of field campaigns present in the respective period under consideration, - "Considerd Period": Time interval which is actually covered with data within the period under consideration [decimal years].
