The present report gives a summary of all the data collected during the field campaign at the beach and in the nearshore zone near Egmond aan Zee, the Netherlands in 1990. The field experiments are executed with the overall goal to improve the knowledge of the processes which govern the depositional and erosional responses of the surfzone, especially near the nearshore bars and ridge and runnel systems. More detailed information of the statement of the problem, including the purpose of the study, the objectives, and the approach to the problem are described in: Nearshore morphodynamics at Egmond aan Zee, the Netherlands· (1989). The field experiments are executed beach near beachpoles 39.000 and 40.000, Egmond aan Zee (Fig. 1) in the nearshore zone and at the about 2 km south of the village. In 1990, one field campaign was executed. This campaign lasted from October until half November. During this period the experiments focussed on the changes in the morphology in the inner nearshore zone in relation to the hydraulic conditions at deeper water (-10 m depth) and the hydraulics and sediment transport processes in the vicinity of the inner nearshore bar. Despite the problems with the installation ot the instruments on the poles and frame, the data sets collected with the measurement sledge and the morphological data will give some valuable informationapout the nature of the morphodynamics of the nearshore zone at Egmond aan Zee. This report gives a description of the data sets of the field campaign. The contents of this report will be first a description of the field experiment site. Then the kind of measurements and data types will be discussed, followed by a chapter with a summary of when the data are collected. Finally, a complete evaluation of the field experiments will be given, including some remarks and recommandations for the field campaigns in the next future.
