Abstract: When water waves are progressing into an ice-covered sea, a part of the wave energy is reflected at the ice sheet edge, however its greater part propagates to the direction of waves as a combined motion of waves and the ice sheet. The interactions between waves and the ice sheet have been investigated, mainly by using theoretical approaches. However, there have been a very few reports of field observations or experiments. In the joint research by Ship Research Institute and Iwate University, an experimental study, as well as a theoretical analysis and a numerical calculation, on the interaction between waves and the ice sheet is projected, and has been performed in the following two steps: Experiment 1: Experiments with a plastic sheet under widely varied experimental conditions Experiment 2: Experiments with a doped model ice In this paper, the properties of the interaction between waves and the ice sheet will be discussed, based on Experiment 1. A linear theory for waves under an elastic sheet was employed to evaluate the deformation of sheet, and the validity of the theory will be also examined by comparisons with experimental data.
