Field measurements were done at the Haringvliet barrier to verify the theory that loading on long structures shows a considerable reduction if wave directionality is taken into account instead of calculating with uniform long crested waves. Wave loads were measured with a row of pressure meters at the barrier. Directional parameters of the incoming wave field were calculated from the signals of a 3-component acoustic current meter, mounted 7.5 meter in front of the barrier. These calculations were different from those used for an open sea, since the waves near a reflecting structure are formed by two highly correlated wave fields. The agreement between the results of the measurements and theory is good.
