Preliminary Results of Breakwater Round-Head Tests

The rational design diagram for Dolos armour should incorporate both the hydraulic stability and the structural integrity. The previous tests performed by Aalborg University (AU) made available such design diagram for the trunk of Dolos breakwater without superstructures (Burcharth et al. 1992). Task IBl of rubble mound breakwater failure modes produces such design diagram for the trunk of Dolos breakwater with a superstructure. The objective of the round-head tests is to produce such design diagram for the Dolosse in the round-head. Thus a relatively complete design diagram for Dolos armour layer will be generated. Furthermore, Task IA will give the design diagram for the trunk of Tetrapod breakwaters. The more complete research results on Dolosse can certainly give some insight into the behaviour of Tetrapods armour layer of the breakwaters with superstructure.
