During the planning of an operation, the seasonal characteristics of the surf in the area should be examined. (paragraph 4)
Steep beaches have gradients of more than 7 percent (1:15), normally have plunging breakers, and typically only have one incoming line of waves in the surf zone at any one time. (paragraph 2-1)
Twenty minutes are required between successive LCAC waves. (paragraph 2-1)
