THE OPTIMISATION OF CREST LEVEL DESIGN OF SLOPING COASTAL STRUCTURES THROUGH PROTOTYPE MONITORING AND MODELLING OPTICREST DE ROUCK Julien 1 , TROCH Peter 1 , VAN DE WALLE Björn 1 , VAN DAMME Luc 2 , BAL Jan 2 1 Ghent University, Ghent, Belgium; 2 Ministry of the Flemish Community, Coastal Division, Ostend, Belgium INTRODUCTION Sloping coastal structures such as seawalls, breakwaters, sea dikes,… are essential in coastal protection and harbour sheltering. Although many research has already been carried out, some aspects of their design still remain unsolved. Actually, crest level design is based on laboratory scale models solely. In the MAST II-project ‘Full scale dynamic load monitoring of rubble mound breakwaters’ (MAS2-CT92-0023) it was stated that wave run-up is underestimated by small scale experiments. Prototype measurements carried out in this project confirm this conclusion. As overtopping and spray are closely related to run-up, it is expected that prototype data analysis results from overtopping and spray measurements may deviate from laboratory experiment results. The main objectives of the OPTICREST-project are • to provide end users with improved design rules for the crest level of sloping coastal structures, based on full scale data and supported by model tests • to verify and to calibrate scale models and to obtain better scale modelling techniques • to calibrate numerical models with full scale data in order to improve the numerical schemes for the simulation of wave interaction with sloping coastal structures • to upgrade, improve and optimise existing run-up monitoring devices and software Major emphasis is put on the collection of prototype data on run-up, overtopping and spray. PROTOTYPE MEASUREMENTS Prototype measurements are carried out at two different sites. At the northern part of the west outer harbour of Zeebrugge (Belgium) a rubble mound breakwater (armour layer consisting of 25 ton grooved cubes) is fully instrumented. In Petten (the Netherlands) run-up data is collected on an impermeable smooth sea dike. In Zeebrugge a measurement jetty has been constructed. Fig. 1 shows a cross section of the Zeebrugge breakwater. The wave climate in front of the structure is recorded by two wave rider buoys which are located at a distance of 150 m and 215 m from the breakwater slope. Wave run-up is detected simultaneously by a spiderweb system and by run-up gauges. The spiderweb system consists of a set of vertically placed stepgauges between the measurement 489
