Abstract: Lake Notoro near the coast of Okhotsk Sea is connected to the Sea by the Notoro Fish Harbor. The Lake has salinity similar to that of the Okhotsk Sea. It is ideal for aquaculture of scallops, oysters and other marine products. During the winter, ice floes drift into the Lake through the channel connecting to the Sea which causes damage to the aquaculture facilities. An ice boom has been proposed to be installed near the entrance of the Lake to prevent the ice moving into the Lake. In this paper, a numerical model study on the dynamic transport of ice, the effect of the boom, and the ice load on the boom spans are presented. The numerical model is a coupled hydrodynamic and ice dynamic model. The ice dynamics component uses a Lagrangian discrete parcel method based on smoothed particle hydrodynamics. The hydrodynamics component uses a finite element method for shallow water hydrodynamics. Results for steady and unsteady simulations for various wind, ice, and tidal conditions are presented.
