Field measurements of directional wave loads on coastal structures
Abstract Data were collected at the Haringvliet barrier to verify the theory that wave loading on long structures is considerably reduced if wave directionality is used in the calculations instead of assuming unidirectional long-crested waves. Wave loads were measured with a row of pressure gauges at the barrier. The directional parameters of the incoming wave field were calculated from recorded signals of a 3-component acoustic current meter, mounted 7.5 metres in front of the barrier, These calculations differed from those used for an open sea, because the waves near a reflecting structure are formed by two highly correlated wave fields. A new method of calculating the wave directional parameters of the incoming wave field from the three orthogonal velocity components was developed. It appears to be successful. The results show that the theoretical model for incorporating wave directional properties agrees very well with full scale measurements. The regression coefficient between theoretical and measured values does not differ statistically from the value 1.
