Abstract :
The error source in assessing the bathymetry by the Dispersive Surface Classificator method is discussed in this paper. The accuracy of the method is high in the deeper areas and is reduced behind the slopes. The identification of systematic correlation of the absolute value of the error with the slope was not possible. The spatial correlation of the error illustrates that the direction of the wave field influences the two neighboring cells in the same direction.
