Abstract

A mathematical theory about phenomena that occur if on a coastal area groynes are constructed. The theory is a simplification: it just deals with one aspect. The starting point in the coastal equation of Pelnard-Considère and a linearisation between the transport along the groyne and the size of the 'step' in the coastline at the groyne. The change of the coastline, caused by changing boundary conditions, by stationary transport and by the 'straightening' of the coast are considered. The conclusion is drawn that in the middle of a row of groynes the same process occur as without groynes, but on a larger time scale. Near the edge of the row there are edge effects, that cause bigger erosion and accretion than without groynes.
