Journal of the Power Division, 1968
Major problems in ice control were encountered at both the St. Lawrence and Niagara Rivers when full hydroelectric development took place. Extensive ice-control measures have been undertaken at both rivers which have proven to be most successful. At the St.

Fracture of River Ice Covers by River Waves
Journal of Cold Regions Engineering, 1995The stresses induced in ice covers by river waves are investigated as a possible mechanism for causing transverse cracks during breakup. The maximum stress levels that river waves can cause in the ice cover are determined over the entire spectrum of waves that may be present at breakup. The ice cover is analyzed as a continuous elastic plate.

Predicting whether and where the ice cover of a river is going to break up as a result of increased runoff, is crucial in such concerns as environmental impact assessment of climatic and hydrologic changes, emergency flood warning and mitigation, and winter hydro-power production.

Forecasting river ice breakup and ice jam flooding
Abstract A mechanical breakup is the breakup of a relatively competent ice cover before the thermal meltout. The potential and severity of jamming and flooding associated with a mechanical breakup are strongly related to the discharge of the spring freshet and the state of the ice cover at the breakup time.Tao Shen, Hung, Huang, Fengbin

Advances in river ice hydrology
Hydrological Processes, 2000River ice is present in nearly all Canadian rivers, for periods ranging from days to many months. Whether moving or stationary, it interacts with the river flow in various ways, resulting in multiple impacts on the economy and ecosystem, and posing a major flood threat to riverside communities.
