Hello! I have a question regarding calculating this for a different situation, and I'm hoping you'd be willing to help. I have the velocity measured at the surface of the water, measured from a buoy. How can I go about solving for the current velocity at a point above the seabed given this?
Hi, you can assume that velocity profile can be approximated by power function u(z)/Us=(z/H)^(1/6), where Us and H are the surface velocity and water depth, respectively.
@@StudyTips4U Thank you so much! One more question - what is the z value if the turbine is in the middle of the ocean? I have a depth of 30 m and a surface velocity of 0.977 m/s, and the base the turbine is on is 0.305 meters. Is the z value the height of base?

Z is the vertical coordinate, at seabed z=0, at the surface z is equal water depth or 30 m for your case.
For example velocity at z=0.305 m is equal
u (at z=0.305m) = 0.977 m/s×(0.305/30)^(1/6)
