For which given combination of the wave steepness, e, and the shoreface slope, s, below, the two-percentile run-up distance (R2%) is the highest? (Consider the significant wave height is the same for all the cases) 1 1 and e = 20 1 and e = 10 1 (a) s = 3 (b) s = 3 1 (c) s = - and e 4 1 (d) s = 20 1 and e = 10 4
