Field tests were conducted at Woodston, Bartley, and Superior-Courtland Diversion Dams in the Kansas River Basin during August 1960 to determine the efficiencies of sediment control structures for excluding sediment from the canal system. Data were also obtained at Cambridge Diversion Dam where a sediment problem existed but the dam had no sediment control structure. Sediment samples and hydraulic data were collected for computing the amount of sediment transported in the rivers and the amount of sediment transported through the sluiceway and canal at the headworks of each diversion dam. At Woodston, Bartley, and Superior-Courtland Diversion Dams where curved guide walls were used as a sediment control structure, the sand load of the river was depositing in the river basin bove the diversion dam at the time of the tests. Very little sand was entering the guide walls at the canal headworks which did not permit a quantitative evaluation of the amount of sand excluded from entering the canal. However, the operating personnel are extremely satisfied with the curved guide walls. The curved guide walls provide an efficient means for flushing sediments deposited above the dam into the downstream river channel either by continuous sluicing or by intermittent sluicing. Author
