| The objective of the present work is to discuss the implementation of an active wave generating–absorbing boundary condition for a numerical model based on the Volume Of Fluid (VOF) method for tracking free surfaces. First an overview of the development of VOF type models with special emphasis in the field of coastal engineering is given. A new type of numerical boundary condition for combined wave generation and absorption in the numerical model VOFbreak<sup>2</sup> is presented. The numerical boundary condition is based on an active wave absorption system that was first developed in the context of physical wave flume experiments, using a wave paddle. The method applies to regular and irregular waves. Velocities are measured at one location... |

| At the Zeebrugge harbour (Belgium) a cross-section of the N.W.-breakwater has been instrumented for the study of physical processes related to the behaviour of a prototype rubble mound breakwater in random wave conditions. Within the EC MAST programme (project MAS02-CT92-0023) this monitoring system has been reengineered and extended to a high-quality full scale data acquisition centre (Troch et al., 1995). The development of the prototype monitoring system to a world-wide unique system with respect to the infrastructure available at Zeebrugge, the instrumentation installed on site, and the data management developed, is briefly summarised. Filed measurements of wave attack in front of the breakwater, and pore pressure response inside the breakwater core,... |

| Continuous seismic profiling using boomer, sparker or pinger sources has gained widespread use in marine site investigations. At a reconnaissance stage, a grid of continuous seismic traverses with adequate orientation and mesh size is able to yield a coherent picture of the structural conditions of subsurface, allowing the definition of areas of main prospective interest. In the early stages of detailed site investigations, seismic profiling forms an efficient tool for the planning of high-cost offshore drilling and penetration testing programs. Keys to success in seismic data acquisition are a matter of careful balancing and matching of source/receiver parameters with the marine and geological environment and with the geotechnical penetration/resolution... |
