On long timescales, the cumulative alongshore transport of sediment at the coastline can play a large role in the depositional patterns. In order to account for this sediment re-distribution along the coastline, a test was conducted to integrate a Delft3D model, similar to what is used in Delft3D-GeoTool with a new and computationally efficient shoreline change model, ShorelineS. In order to accomplish this, a well-studied case study was chose: the Old Rhine Delta.
