Stability of cube armoured roundheads exposed to long crested and short crested waves

The paper presents an update of the stability formulae by Maciñeira and Burcharth (2007) for cube armoured roundheads exposed to long- and short-crested waves. Reanalysis of former model test results and supplementary new model tests leads to a more precise set of formulae covering long-crested and short-crested waves. The formulae are valid for two layers of randomly placed cubes, ranges of head diameter, slope, cube mass density and wave steepness.
