Laboratory studies were made on a 6-inch diameter circular pile, using both regular and irregular waves. Detailed force analyses were made of both sets of data. Harmonic analyses of the total horizontal force acting on a pile was made in order to examine carefully the mass coefficient and drag coefficient. An attempt was made to relate these coefficients to certain dimensionless parameters. Dimensional analysis showed that the coefficients depended not only upon Reynolds number, Froude number, and Iversens modulus, but also upon the water depth-wave length ratio dL and the time parameter tT.
