| Abstract |
The morphological behaviour of estuaries is complex and at present (1995) not well understood. Ebb and flood channels play an important role in the morphological behaviour of an estuary.In order to get more insight in the morphological behaviour of such systems it is studied whether a 1-D morphodynamic network model gives insight in this problem. This insight can be important for e.g. maintenance dredging, river training, and the design of navigation channels. As in estuaries a static equilibrium profile cannot be defined, first a condition for a dynamic equilibrium profile is derived. Next the dynamic equilibrium of a short basin is analysed with a single-channel and a simple two-channel model on an analytical base.Subsequently the ebb and flood channel system 'Pas van Terneuzen - Everingen' of the Western Scheldt is taken as a reference case and the available data is gathered. Finally the reference case is schematised to a numerical model. In this model the morphological development is considered. |
