Rowlesburg Dam will be a gravity-type concrete structure, 271 ft above the floor of the stilling basin and 1695 ft long. Flow regulation will be provided by a high overflow spillway consisting of seven 45-ft-wide bays and six 5-ft-8-in.-wide by 10-ft-high sluices with inverts 221 ft below the spillway crest. The 320,000-cfs design flood will be passed by combined flow with the reservoir at el 1638.5. An additional sluice with multilevel intakes in the faces of the water-quality control tower near the left abutment was included in the model to check the feasibility of the proposed scheme of selective withdrawal. Tests were conducted on a 1:20- scale sluice intake model and a 1:60-scale comprehensive model to study hydraulic performance of the spillway, verify the adequacy of the spillway and sluices for both separate and combined-flow operation, verify and/or refine the stilling basin design, study approach and exit channel conditions, evaluate the effectiveness of the water-quality control tower and sluice in selectively withdrawing water from desired levels, and investigate pressures in the sluice intake. The stage-discharge curve for combined uncontrolled spillway and sluice flow developed from model test results is in very close agreement with the computed curves. The capacity of the structure is adequate. A satisfactory stilling basin design was developed. The sluice intake model tested permitted development of a more economical and cavitation-free intake design. A multilevel bulkhead slot functioning as a 25-ft-wide sharp-crested weir was unsatisfactory as a means of selectively withdrawing flows from the top 15 ft of the reservoir without withdrawing from a lower stratum. A multilevel scheme with a 25-ft-wide by 2.5- or 5-ft-high orifice was found to be superior to the weir scheme but still fell far short of the desired operating characteristics. The sponsor will review the problem and consider other withdrawal schemes.
