DEVELOPMENT OF PRACTICAL BREAK-UP PERIOD ESTIMATION METHOD BASED ON ICE SHEET THICKNESS EQUATION

Abstract

 The purpose of this study was to develop an estimation method for the break-up period that occurs before ice jams occur. Ice sheet thickness decreases during the break-up period. Ice sheet thickness calculation considering snow cover, snowmelt, rainfall are highly accurate in their calculated values. The calculated minimum water temperature was found to be an important value. The acceleration of ice sheet thickness variation P_B, was used to estimate the break-up period. This method uses six input values, estimated the break-up period on the safe side. The ice sheet thickness when fully frozen is an important parameter too.
