Figure 7-105. Wave pressures from broken waves: wall landward of still-water 

 line. 



The dynamic pressure is assumed to act uniformly over the broken wave height 

 at the structure toe h' , hence the dynamic component of force is given by 



R = p h' = 



m m 



and the overturning moment by 



wd, h

The hydrostatic force component is given by

and the moment resulting from the hydrostatic force by
