Breakwater design calculation

WebThe next step is to define a material for the armour layer, in this case we will first design a breakwater with rock as armour layer. We use the standard rock grading defined in the standard NEN-EN 13383 (2002) with a density of 2650 / 3, which is the default value. NEN=bw.RockGrading(rho=2650) We are now ready to design a breakwater.
