|Paragraph=Based on long term bathymetry research in the Eastern Scheldt delta transects with and without oyster reefs were compared (Figure 1). Based on height differences, the transects sedimentation and erosion rates were calculated and used to determine if there was a difference between transects without oyster reefs and transects crossing oyster reefs. The overall erosional trend of the Eastern Scheldt tidal flats became clear: the mean observed erosion was -0,012 meters per year. When considering the transects including oyster reefs a mean accumulation of sediment of +0,007 m per year was observed.
The results of this research suggest that these ecosystem engineers, covering almost 10 km<sup>2</sup> in the Eastern Scheldt, slow down the erosion of the tidal flats, as they act as sediment accumulators and stabilizers. An estimated volume between 70 000 m<sup>3</sup> (comparison to a stable situation) and 190 000 m<sup>3</sup> (comparison to the erosional tidal flats) of sediment is stabilized per year on tidal flats in the Eastern Scheldt due to the presence and effect of oyster reefs {{Cite|resource=File:Effects of natural oyster reefs on the sediment balance.pdf|name= (Salvador de Paiva and De Vries, 2014)}}.
