A study has been made of the forces generated on a submerged horizontal cylinder, held remote from the channel bed, due to the passage of a solitary wave. The horizontal cylinder was positioned with its major axis parallel to the direction of the wave crest. The vertical and in-line forces were measured using a force balance. The horizontal fluid velocities were measured using a Hot Film Anemometer (HFA). The drag and inertia components of the force are separated in the analysis by three different methods and correlated with Reynolds, Keulegan & Carpenter and Inverson's numbers. This study investigates a basic wave I structure interaction using Morison's equation. This supposes that the total force on a submerged object is the simple superposition of two well established force components, namely the drag and inertia components. History effects are removed by using the fluid environment generated by the solitary wave, which is unidirectional accelerated motion in still water. Measurement and validation of the fluid flow characteristics are made, to ensure a high degree of certainty for the results. The objective is to establish a relation by which the coefficients used in Morison's equation can be accurately determined from basic wave characteristics.
