A MODEL OF MORPHOLOGICAL BEHAVIOR OF TIDAL BASINS

A one-dimensional semi-empirical model is presented, which simulates t he morphological behaviour of a tidal basin in response to a change in one or more of the extrinsic conditions. The model is based on three equilibrium parameters: the channel cross-sectional area, the flats' s urface area and the flats' level. The model is tested for three scenar ios, namely a partial closure, an accelerated sea level rise and a cha nge in the tidal range. It is verified by simulating changes in the Fr iesche Zeegat, the Netherlands, for which model results are compared w ith measurements.
