Bedform (dune) properties calculated from multibeam bathymetric survey from the Weser Estuary between 2009 and 2014 are given. This includes the BEP bedform properties (crest position, date of survey, mean depth of bedform, length, height, bedform asymmetry, mean and maximum angles of the flood and ebb lee sides, normalised horizontal and vertical positions of the maximum angles, height, length and mean angle of the ebb and flood steep faces (if present) and normalised position of the beginning and end of the steep faces), and the crestline properties (positions of the crestline middle point, crestline length, mean and standard deviation of crestline orientation, standard deviation of crestline height, and non-dimensionnal span).
