AbstractThe melting process of lake and river ice covers differs from that of snow covers. Solar radiation causes surface melt, internal melt and, under some conditions, melting at the ice-water interface of an ice cover. Lake and river ice influence the distribution of snow available for melt in the spring and affect the shape of the winter and snowmelt hydrograph. The water equivalent of white ice representing potential melt water may be sufficient to affect snowmelt hydrographs on watersheds with a high density of lakes. Winter runoff can be affected by river ice conditions thus changing the amount of water held in storage immediately prior to the snowmelt period. The time distribution of snowmelt and maximum water levels are influenced by ice jams during spring runoff.
