Q2) 1. Explain the difference between fetch limited and duration limited wave formation. II. A vertical steel cylinder 3.8 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 6.0 m with a wave period of 8 sec. Assume that the Reynolds number is less than 5x105. III. Estimate volumetric bed load transport rate using Shields bed load equation, if flow through a rectangular channel is 25 m3/s. The channel slopes at 1 in 2500, has a Manning's n value of 0.035, and a bed width of 30 m. The channel boundary is made of fine-gravel with specific gravity of 2.65 and average size of 2 mm. Assume that the Shield's parameter = 0.056.
