## Principle

The evolution of the coastline of French Guiana between Cayenne and Kourou between 1986 and 2006 is modelled as resulting from the combined effect of waves, currents and the displacement of a mudbank 20 km long and 5 km wide along the coast. The 'chenier' (immobile, in green) and the initial status of the 'coastline' (mobile, in yellow) are read from a shapefile. A forcing relation between 'ocean' on 'coastline' describes empirically the deformation of 'coastline' as a function of daily waves, prevailing currents, and also the position of the mudbank which acts as a protection against the waves.
