The estimation of wave loads on very large flouting structure is usually done by an empirical or a computational approach. The computational approach usually assumes two types. Some use the Laplace equation or potential flow and some take the Navier-Stokes equation or viscous flow analysis. In this study, the interaction between wave and elastic plate is investigated by using viscous flow assumption. It is coupled with the elastic plate equation. Numerical solution is carried out with finite difference method in form of upwind scheme. The displacement of elastic plate is simulated numerically. Numerical results are compared with the numerical results of Basirat Tabrizi and Kouchaki Motlaq for potential flow and with the numerical results of Ohkusu and Namba and experimental results of Kashiwagi for viscous flow. The results show that viscous flows have more damping effect on displacement of elastic plate than non-viscous flows.
