3.2F Velocity Profile near Natural Interfaces The wind velocities listed in Table 1.1F were observed above a crop can near Davis, California, in July 1962. Comoute Jandy, (kmi for each time. Based on the values of and y, what type of crop might be present? 1.2G. Viscous Sublayer at Seafloor Caldwell and Chris made measurements of currents reat the seafloor a site on the Oregon continental shelf in /w of water. The surface sedime are silty sand with a mean grain diameter of 0.01mm No bedforms w present to influence the flow significantly. Flow measurements with a hea thermistor, taken above the sediment, appear in Table 1.2G Table 3 Table 32G
