ICE CONSTRUCTION: SURVEY OF EQUIPMENT FOR FLOODING.
Two surface-flooding techniques for improving natural ice areas have been developed. Confined flooding, in which the flood is retained by natural boundaries and dikes, is used principally for filling and leveling thick natural ice areas. Free flooding, in which the outward flow of water is retained...

Two surface-flooding techniques for improving natural ice areas have been developed. Confined flooding, in which the flood is retained by natural boundaries and dikes, is used principally for filling and leveling thick natural ice areas.

This survey shows that adequate surface pumping units and flood distribution systems have been developed for confined flooding, and subsurface pumping units are being developed for free flooding. Mobile power-handling equipment is available for moving, lifting, and placing the pumps and other heavy gear required for ice construction, but the available man-handling gear for this work is less than adequate.
