Abstract: This paper presents a simple new method to separate damped incident and reflected waves on the muddy bottom and to estimate their dissipation ratios from a simultaneous recordings of the wave profiles. The reflection coefficient of the sea wall is approximately evaluated based on the resolution results. On the other hand, the method of the estimation of the wave-damping ratio by using the mud motion theory is also described. Both the numerical and laboratory experiments are carried out to verify the resolution technique. Finally, the damping ratios evaluated by the proposed technique are compared with those obtained from the theoretical analysis of mud motion.
