Idealised modelling of estuaries

For geometrically idealised estuaries mathematical methods are used to investigate the expected effects of deepening of the estuary, with regard to tidal penetration, salt intrusion and residual currents which are of great importance for the SPM dynamics. Such modelling approach we apply in research of the regime-shift hypothesis in the Scheldt estuary that examines the possibility of a long term evolution towards a larger average SPM concentration in the Sea Scheldt.
