Summary

Dean (1991) have proposed the concept of an equilibrium beach profile. Dean (1991) derived the equilibrium beach profile model with the wave energy dissipation similar to other previous works (e.g., Bruun, 1954). The equilibrium beach profile equation is very simple, but has been used by many researchers for coastal engineering.

Model formula

Dean (1991) suggested a simple equilibrium beach profile equation based on the wave energy dissipation as follows:

h=Ay^(2/3)

h : the water depth
y : the seaward distance
A : the Dean parameter
