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.

Numerical modelling of the impact of sea level rise on large tidal inlet/basin systems
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.
