SAND TRANSPORT ON THE SHOREFACE OF THE HOLLAND COAST

J.A. Roelvink, M.J.F. Stive

Abstract


Yearly averaged transport vectors have been computed along a number of rays, perpendicular to the coast, on the shoreface of the Holland coast. Variation in time and space of wave conditions, tidal flow and long-term average near-bottom flows are considered in fine detail. Special attention is paid to various correlations, both between different velocity components and between velocity and water level, as these correlations play a major role in determining direction and magnitude of net transports. Calibration is performed against both long-term and short-term observations of developments. The resulting transport pattern helps to explain some observed large-scale developments of the Dutch coast.
