UNCONVENTIONAL POWER SOURCES FOR ICE CONTROL AT LOCKS AND DAMS

This study of the feasibility of various unconventinal power sources for ice control at lock and dam installations, reviews ice-control practices at several sites. It was found that at L&Ds, the primary ice growths to be controlled by heat application are, ice-collar formation along lockwalls, particularly in the miter-gate recess, and dam gates. The most unconventional power source to meet the requirements appears to be hydroelectric power generated at L&Ds by means of small, portable, power-barge plants. Direct heating of lockwalls, lock miter-gate recesses, and dam-gate pier-walls by means of electrical heaters embedded in concrete walls is the best approach to controlling ice growth on lockwalls and dam gates. These and other findings are discussed.
