Beltaos. Burlington, Ont. : Hydraulics Division, National Water Research Institute, Canada Centre for Inland Waters, 1985. 1 v. (various pagings) : ill. NWRI contribution ; 85-139 "November 1985". Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references: p. 19-20. "Ice cover failure at spring breakup is governed by thermodynamic and physical laws. In principle therefore, it is possible to describe the initial breakup process. This paper describes possible mechanism, backed up by observation, for the breakup process and the subsequent form of the loose ice cover. The analysis brings order and insight to the early stages of breakup which is an essential first step to logical forecasting and management of rivers subject to spring ice jams"--Management perspective, p. i.
