This paper presents the application of a morphodynamic model based on 2D reduced-physics principles to
investigate morphology change of a complex estuary inlet system in the United Kingdom. The model
combines a simple governing equation with a set of measured bathymetry data in order to model
morphology change. The modelling method suggests that this simplified approach is able to recognise
principal medium term morphodynamic trends in the estuary. However, the length and quality of the
estuary bathymetry data set limits the applicability of the model to inter-annual scale
