Field investigations in the tow study programme for coastal sediment transport in the Netherlands

Field campaigns were conducted in 1981 and 1982/83 on the Dutch coast near Egmond. Measurements were made of surface elevations, water velocities and sediment concentrations in 3 to 8 surf zone locations and 2 to 5 offshore locations simultaneously. A total of 50 measurement series was obtained under a variety of weather conditions, resulting in offshore wave heights of 0.2 to 4.6 m. A descriptionis given of the field set up, the instruments and measurements, and the collected data. The quality of the various measurements systems and the data produced has been investigated extensively by intercomparison of instruments and devices in the field. The results are reported here.
