Classilied polygon data set of various sedimentological parameters for the German Bight area. Polygons are based on a triangulated model grid (spatial resolution: 250 m * 250 m).

Parameters:

- "Median_Grain_Size": median grain size (D50) of interpolierted grain size distribution,

- "Mean_Grain_Size": mean grain size´ of interpolierted grain size distribution,

- "Sorting1": sorting after Trask (1932): sqrt(D75/D25)

- "Sorting2": sorting after Folk and Ward (1957): (phi84-phi16)/4+(phi95-phi5)/6.6

- "Skewness": Skewness after Folk and Ward (1957): (phi16+phi84-2phi50)/2(phi84-phi16)+(phi5+phi95-2phi50)/2(phi95-phi5)

- "Kurtosis": Kurtosis after Folk and Ward (1957): (phi95-phi5)/2.44(phi75-phi25)

- "GSF_micrometer": content of sand fractions (half phi grad intervals) [%], 63 to 2000 micrometers

- "PredominantSandFractions": spatial distribution of sediment fractions with a coontent 50 % / 20 % - 50 %.

Data were generated within the framework of the German Coastal Engineering Research Council project AufMod ("Development of integrated model systems for the analysis of long-term morphodynamics in the German Bight", 01.11.2009-31.12.2012).
