Abstract
The response of a large tidal inlet/basin system to Climate change driven sea level rise, in combination with local subsidence is simulated with two very different numerical modelling approaches: process-based and scale-aggregated. Delft3D (process-based) and ASMITA (scale-aggregated) models are used to simulate the morphological evolution of a schematised inlet/basin system representing the Ameland inlet in the Dutch Wadden Sea for a Relative Sea Level Rise scenario (RSLR) of 10 mm/year over a 25 year period. While the quantitative forecasts of the two models are different to each other, both models qualitatively indicate, over the 25 year simulation period, (a) a flood-dominant transport system which agrees with the contemporary measurements of the Ameland inlet, and (b) RSLR driven enhancement in the sediment transport. The ASMITA suggests stable tidal flats with an RSLR of 10 mm/year while the tidal flats diminished in the Delft3D.
