Abstract:	The North Sea is a very dynamic area, where different morphological features appear, from small ripples to large tidal sand banks. We extended the work of Hulscher and van den Brink (2001), who were the first to compare an idealized model, of large-scale seabed patterns with data of seabed patterns in the North Sea. Firstly, the model is adapted by implementing a critical shear stress. Secondly, a variable viscosity profile based on Komarova and Hulscher (2000) is introduced in the model. And thirdly, the model is extended by including a grain size dependency. The adaptations made to the model of Hulscher and van den Brink lead to more accurate predictions of large-scale bed forms that occur at the sea bed of the North Sea.
