MS 1/ Given: A smooth impermeable seawall has a i-on-2 slope fronted by a 1-on-10 bot- tom slope similar to that shown in Fig. 20-12. The depth at the toe of the structure is 2.1 m, and the bottom slope extends seaward to the depth of 18 m. The deep-water wave height is 3.5 m, and the wave period is 8 sec. Estimate the wave runup.

Solution

H/gt² = 3.5/(9.81*8²) =0.0055

cot = 2
