IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
In this paper we use a 2D process-based model to hindcast morphodynamic behavior of the Western Scheldt estuary. The
periods of 1860-1970 (110 years) and 1905-1970 (65 years) are simulated. We compare the results to a historically unique
dataset of bathymetric maps. The results show that the model results get better over time. The results show that the model
is capable of simulating the large scale erosion and sedimentation that has occurred in the considered period. We attribute
this to the self-organization of both the model and reality. The interaction between the major tidal forcing and the estuaries'
fixed outline overrules other uncertainties over long time scales. Our research shows that process-based models applied
in confined environments and under constant forcing conditions may perform well especially on long time scales. This
makes them potentially suitable for centennial time scale forecasts related to, for example, climate change.
