Verhagen, H.J. (author), Mertens, M. (author)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%...conference paper 2009

Verhagen, H.J. (author), Van Vledder, G.P. (author), Eslami Arab, S. (author)Modern design formula for coastal structures (like rock stability formula and overtopping formula use wave parameters (H2% and Tm-1,0) which are not readily available from standard boundary condition wave data. For transforming values like Hs and Tp to the parameters used in the new formulas, often-fixed conversion factors are used. However,...conference paper 2008

Verhagen, H.J. (author), Reedijk, B. (author), Muttray, M. (author)Experience has shown that stability parameters for breakwater armour are different for steep and shallow foreshores, as well as for deep and shallow water. A change from a deep water spectral information (Tm0) to shallow water spectral information (Tm-1,0) does not completely explains this difference. Tests have shown that stability also depends...conference paper 2006
