Framework for Control of Dynamic Ice Breakup by River Regulation
This report describes and classifies the entire range of ice breakup behavior, from the thermal to dynamic, to provide order to this complex process. The theory and model of the authors are refined, building on the concept of an intrinsic relationship between river waves and dynamic ice breakup. A f...
