Numerical simulation of freeze-up jamming in a skim ice regime

Cold Regions Science and Technology, 2021
Abstract Freeze-up jamming on regulated rivers is an important aspect of cold regions hydropower operations. The timing and nature of freeze-up jamming has a role in reducing effects to winter discharge conveyance. In northern regions with very mild-sloped rivers, skim ice run is of considerable importance to the formation of a thin and stable cover ...

St. Lawrence River Freeze‐up Forecast

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1986
In this study a method for making long‐range forecasts of freezeup dates in rivers is developed. The method requires the initial water temperature at an upstream station, the long‐range air temperature forecast, the predicted mean flow velocity in the river reach, and water temperature response parameters.

Thaw and Freeze-Up: Prague 1968

International Journal: Canada's Journal of Global Policy Analysis, 1969
Czechoslovak "democratization" from January 1968 on and its rude interruption in August marked a watershed in the evolution of world communism and perhaps a turning point in international affairs and world history. The Prague "spring" represented an effort at reform going far beyond any previous "liberalization" of a communist state.

Freeze-Up Processes in the Alaskan Beaufort and Chukchi Seas

OTC Arctic Technology Conference, 2012
Abstract This paper characterizes the processes that presently occur during freeze-upin the Alaskan Beaufort and Chukchi Seas, based on joint-industryinvestigations conducted in 2009-10, 2010-11, and 2011–12. The studies weredesigned to address five specific objectives:describe the ice conditionsthat evolve during ...
