A relation by Andreanov between wave-energy loss and nearshore slope, when combined with the TMA wave-energy constraint, is shown to closely approximate the classical Bruun/Dean shape. Further, it predicts a bar array and a swash zone, and can be applied to cases of constrained maximum wave-orbital velocity.
