Low Cost Liners for Canal

Abstract

Because of the increasing urgency of conserving water lost from unlined irrigation canals, the Low Cost Liners for Canal Program was inaugurated by the Bureau of Reclamation in June 1946 as a concerted effort to develop lower-cost linings. An interim report, issued in 1946, outlined the broad scope of the program and presented information available at that time on types of linings and their service records.

\In the past two years, the program has been advanced by laboratory and office research, surveys of installations, seepage determinations, field experiments, and equipment development. This report records the progress made in developing lower-cost linings. In many phases of the program, accomplishment has been limited, and the many problems that remain unsolved emphasize the complexity of the undertaking.
