Abstract

Wave force data have been reanalyzed for drag and inertia coefficients. These data are the field results of Wave Project I and II and consist of water surface elevations and forces on piles of various sizes at different elevations within the water column. The analysis is based on the stream function wave theory and Morison's equation, resulting in drag (C//D) and inertia (C//M) coefficients including a dependency on Reynolds number. Principal findings are a somewhat obtained P. M. Aagaard and R. G. Dean. Free surface effects include a run-up on the piling and an associated local modification in drag coefficients, resulting in reductions in overall force and moments.
