The Wadden Sea consists of a series of tidal lagoons which are connected to the North Sea by tidal inlets.Boundaries of each lagoon are the mainland coast,the barrier islands on both sides of the tidal inlet,and the tidal watersheds behind the two barrier islands.Behind each Wadden Island there is a tidal watershed separating two adjacent tidal lagoons.The locations of the tidal watersheds in the Wadden Sea are not fixed.Especially after a human interference in one of the tidal lagoons,a tidal watershed can move and thereby influence the distribution of area between the lagoons. This appears to be important for the morphological development in not only the basin in which the interference takes place,but also in the adjacent basins.This paper describes theoretical analyses and numerical modelling aimed at improving the insights into the location of the tidal watersheds,their movements,and the impact of the movements of tidal watersheds on the morphological development of a multi-basin system like the Wadden Sea.

The Wadden Sea consists of a series of tidal lagoons which are connected to the North Sea by tidal inlets. Boundaries of each lagoon are the continental coast, the barrier islands on both sides of the tidal inlet, and the tidal watersheds behind the two barrier islands .Behind each Wadden Island there is a tidal watershed separated two adjacent tidal lagoons. The locations of the tidal watersheds in the Wadden Sea are not fixed .Especially after a human interference in one of the tidal lagoons, a tidal watershed can move and therefore influence the distribution of area between the lagoons. This appears to be important for the morphological development in not only the basin in which the interference takes place, but also in the adjacent basins. This paper is theoretical analysis and numerical modeling aimed at improving the insights into the location of the tidal watersheds, their movements, and the impact of the movements of tidal watersheds on the morphological development of a multi-basin s ystem like the Wadden Sea.
