(a) Briefly describe various bed-forms that will develop in natural watercourses. (b) A wave of height 2.2 m breaks onto a vertical wall whose base is 3 m below mean sea level. The depth of the water from the mean sea level to the seabed is 2.5 m. Calculate the maximum force per unit length on the wall and the bending moment at the base of the wall. (c) A vertical steel cylinder 4.2 m in diameter constitutes one leg of a small offshore structure. Calculate the maximum likely drag and inertia forces due to a deep-sea wave of height 6.5 m with a wave period of 12 sec. Assume that the Reynolds number is less than 5x10%.
