The geo-morphology of the Western Scheldt estuary, one of the two remaining open estuaries in The Netherlands, has been strongly influenced by human interference over a number of centuries. In recent years the dredging and dumping activities has increased from less than 0.5 Mm3/year in 1950 to over 15 Mm3 in the 1975. In 1997 a second deepening program for the navigation channel is started and a new dredging program in initiated.For the optimalization of the dredging and dumping operation and for the identification of the impact of the operation to the long-term morphological development of the estuary the ESTMORF model was built. ESTMORF is a program package for 1D network modelling of long-term morphological development of estuaries and tidal lagoons. It is based on empirical relations for the morphological equilibrium, combined with hydrodynamic and sediment transport models based on physical laws. The present paper describes the calibration/verification of Western Scheldt the model using data in the period 1968-1993.
