Abstract

The analysis of a large bathymetric data set of a part of the central Dutch coast reveals that a multiple bar system as a whole may exhibit three-dimensional behaviour. This behaviour is cyclic and consists of a net offshore migration of the bars, with the outer bar fading away and with a new bar being generated near the shoreline. The bar behaviour becomes three-dimensional because parts of the 25 km long bar system are not in the same phase of the 15 year cycle. Parts of the bar system are in the same phase over alongshore distances of typically 6 km. Transition areas between the 'in phase' parts have a typical length of 2 km. It is hypothesised that the cyclicity in the behaviour of the bar system is governed by the behaviour of the outer bar. Further, it is proposed to adapt the length of the coastal stretch that is monitored for morphological changes during field experiments to the length scales of the three-dimensional bar system behaviour.
