The aims of this paper are: to publish some available coastal measurements and computations of more than local importance, to investigate the influence of groynes in practice, and to investigate the motion of the gullies in the outer deltas. The following conclusions are drawn: The gross littoral drift along the Dutch coast is of the order of 1.5 to mln m3/year; (computed with the CERC- formula) the resulting net drift is mostly within the order of accuracy of the computation. The erosion of the areas with groynes was much less than the erosion of the adjacent areas; partially this effect is due to lee-side scour but mainly to decreased erosion in the protected areas. The gullies in the outer deltas on the Wadden mainly rotated clockwise, which is probably the direction of the resultant transport there.
