Gain insight on the distance from the baseline to the coastline, the local littoral drift rates and accumulated transport along the coastline with the Coastline Evolution module. This module is based on a one-line theory, in which the cross-shore profile is assumed to remain unchanged during erosion/accretion. Thus, the coastal morphology is solely described by the coastline position (cross-shore direction) and eventual changes of dune geometry at a given long-shore position.
