A wave with a period of 8 seconds and a height of 5.5 meters propagates in a water depth of 15 meters. What are the horizontal and vertical velocities and accelerations at an elevation of 5 meters below the still water level when the phase angle is 60 degrees?

A regular wave has the following properties in 50m depth water: wave height: 3.5 m; wave period: 11 sec; wave angle: 30 degrees. Using linear wave theory, estimate the wave height in 6m depth, assuming straight and parallel depth contours.

A concrete coated steel gas pipeline is to be laid between two offshore platforms in 100 m water depth where the maximum environmental conditions include waves of 20 m wave height and 14 s period. The pipeline outside diameter is 46 cm, and the clay bottom slope is 1 on 100. Determine the submerged unit weight of the pipe. Assume linear wave theory is valid and that the bottom current is negligible.

A wide channel is 1 m deep and has a velocity of flow v as 2.13 m/s. If a disturbance is caused, an elementary wave can travel upstream with a velocity of (a) 1.00 m/s POI (c) 3.13 m/s (b) 2.13 m/s (d) 5.16 m/s
