Prediction of wave time-history using multipoint measurements

The formulation for wave prediction using multipoint measured data is derived for the short crested waves. The formulation can be applied not only for the stationary process but also the non-stationary process. Based on this formulation, a convolution integral formula which represents the relation of free surface elevation between multipoint measurement and target point prediction is obtained. Examples based on numerical experiments of long crested waves show that prediction error is small when the prediction time is short and the measurement point is sufficiently far from target. Although it is found that the accuracy of the prediction based on the proposed method has a limit for short crested waves, the agreement is fairly good.
