Overtopping Velocity of Ice Floe on the Breakwater due to Wave Action

Abstract

The Okhotsk Sea coast of Hokkaido is covered with drift ice in winter. When ice floe concentration is low, sometimes overtopping of ice floe occur at breakwater due to wave action. Fishing boats and pipelines behind breakwater hava been dameged by the ice floes. It is required that ice control facilities are constructed. In order to design the facilities, we have to know the overtopping velocity of ice floe on breakwater.
We report on the systematic experimental results on overtopping of ice floes and its mechanisms.
