(a) How does the maximum wave setup depend on the beach profile if the spilling breaker assumption applies?

(b) Suppose that the initial break point occurs in accordance with H_b
= κ_hb
but that for shallower depths the wave height initially is less than, but later follows, the relationship H_b
= κ_hb. Will the resulting maximum setup be greater than, the same, or less than the case in which H_b
= κ_hb
? Discuss your answer.

(c) Suppose that the initial break point occurs in accordance with H_b
= κ_hb
but that, for shallower depths, the wave height initially is greater than but later follows the relationship H_b
= κ_hb. Will the resulting maximum setup be greater than, the same as, or less than the case in which H_b
= κ_hb? Discuss your answer.
