## 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 an equilibrium beach profile model based on the wave energy dissipation as follows: | ||

```text | ||
h=Ay^(2/3) | ||
h : the water depth | ||
y : the offshore distance | ||
A : the beach scale factor | ||
``` | ||
y : the seaward distance | ||
A : the Dean parameter | ||
