.... The experimental arrangement and dif- ferent test conditions achieved are major topics of the presentat ion. The i nf 1uence of seabed roughness (boundary layer effects) on both oscillatory and steady loads have been investigated for a pipe on a flat seabed. The measured forces do not conform to the simple...

... ABSTRACT The flow boundary layer was studied with measurements of tidal current and wave velocity made at 0.10, 0.25, 0.50, 1.00, 3.00 and 5.00 m above the seafloor at two locations in the North Sea in 70 m and 102 m water depths. The data cover a range of combined current and wave conditions...

... ABSTRACT The objective of the field measurement program was to provide accurate data for flow velocities in the seabed boundary layer and other parameters having influence on the flow boundary layer, especially storm waves, suspended sediment concentrations and bottom roughness. Measurements...
