Sedimentological Parameters Model Grid Points (Project AufMod)

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). Various sedimentological parameters processed as products for the German Bight area were calculated from interpolated grain size distributions (spatial resolution of model grid 250 m * 250 m):

- "Median_Grain_Size": Median-Durchmesser (D50) der interpolierten Kornsummenkurve

- "Mean_Grain_Size": Mittelwert des Korndurchmessers

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

- "Sorting2": Sortierung 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 %.
