Abstract

Equilibrium beach profiles have been investigated in the laboratory for two beach materials, 0.22 mm marine sand and 1.55 mm crushed coal. Analysis of the results confirms that the dimensionless fall velocity H0/Tw is an important parameter influencing both surf zone hydraulics and the form of the resulting equilibrium profile. Beach permeability also significantly influences the hydraulics within the beach face and it has been found that both H0/Tw and the parameter wf/w, the ratio of the fluidizing velocity to the fall velocity, influence the form of the equilibrium profiles of permeable beaches.
