Abstract : Operation of lock and dam installations is made troublesome and hazardous by ice growth along lock walls and by freezing of gates to ice covers. Since considerable amounts of power are required for ice control, lock operators are interested in utilizing economical power sources other than that generated by commercial utilities. This study attempted to determine the feasibilities of using several unconventional power sources for ice control at navigation locks and dams. Considered were sensible heat from groundwater, solar power, wind power and portable hydroelectric sources. Only portable hydroelectric power is feasible. Groundwater is at best of marginal feasibility, and solar and wind power sources are unreliable.
