Training of coastal engineers to work in a non-engineering environment

Integrated Coastal Zone Management (ICZM) is an interdisciplinary process by definition. Individual actors in CZM need to cooperate and communicate to come to an optimum management strategy for the coastal zone. Because engineers focus on finding the “best” solution in engineering terms, they often are quite surprised that in the end of the day...

A database of major breakwaters around the world

This paper introduces a co-operative project between HR Wallingford UK (HRW) and Delft University of Technology, Netherlands, (TUD) to develop, populate, and then to apply a database on all major breakwaters around the world. It builds on, and revives, similar initiatives that originate in the late 1970s. The paper describes the objectives in...

Recent laboratory tests with elastomeric revetments

A new construction method of Polyurethane (PUR)-bonded revetments has been tested successfully on various locations in Germany, in the Netherlands, in France, and in the UK. See also the presentation of Bijlsma on this ICE breakwater conference. This year a series of large scale test in the GWK-facility in Hannover have been executed. This...

Riprap stability for deep water, shallow water and steep foreshores

In the Rock Manual [2007] two sets of equations for the determination of rock stability in breakwaters armour layers are presented. One set is the original formula presented by Van der Meer [1988], valid for deep water conditions. This set uses the parameters Hs and Tm. The other set is an adaptation of these formulae, using the parameters H2%...
