Seasonal variation in suspended particular matter (SPM) is often observed in the Scheldt estuary. As part of it, the estuarine turbidity maximum (ETM) zone also exhibits different characteristics in different periods of a year. There are many reasons behind this complex phenomenon, the change of boundary forcing and the biological effects. This study tries to understand the ETM response to the change of boundary forcing in a seasonal scale. For this purpose, a schematic model of the Scheldt estuary is created, and a 3-class population balance equation based (3CPBE) flocculation model is incorporated. The model results reveal that the flocculation process is crucial for reproducing the ETM, and more importantly, its seasonal variation.
