Following the PIANC PTC II working group on Analyses of Rubble Mound Breakwaters it was, in 1991, decided to form Working Group (WG) n° 28 on Breakwaters with vertical and inclined concrete walls””.
The scope of the work was to achieve a better understanding of the overall safety aspects in the design of this important class of breakwater.
The chairmanship of Prof. H.F. Burcharth was confirmed in 1991, and all members of the WG were appointed in September 1992. Due to the foreseen start, by January 1993, of the three years duration European Community MAST II research project “”Monolithic Coastal Structures”” (MCS), it was proposed to run the WG 28 parallel to the MCS project in order to be able to include the relevant findings of this project in the WG 28 work. This coordination was accepted by PIANC and turned out to be very fruitful and easy as some members participated in the MCS project.
The start-up meeting was held February 1993 at University of Hannover. Further meetings were held October 1993 at CEDEX in Madrid, April 1994 at Port Authority of Genoa, April 1994 at Institution of Civil Engineers London, and February 1995 at the Technical University of Berlin. The final meeting was held in September 1996 at Delft University of Technology.
For various reasons the completion of this main report was delayed. This however, gave the opportunity to make use of the results of the European Union PROVERBS project and other recent results. Final editing of the main report was done in a meeting of the subgroup leaders in Delft, August, 2001.
The outcome of the work is the present main report, which summarises the contents of four subgroup reports, which can be purchased from PIANC.”
