Book excerpt: A 1:40 Froudian Scale model was used to investigate the hydraulic performance of the Lower Monumental Dam spillway, stilling basin, and tailrace for dissolved gas reduction and stilling basin apron scour. The model reproduced a 2-1/2 bay section of the spillway and portion of the nonoverflow section between the spillway and navigation lock. Performance characteristics of two spillway deflectors were evaluated. The existing deflector (12.5 ft long horizontal with small fillet radius for transition from spillway to deflector) was recommended at el 434.0 because of its slightly wider tailwater range for operation in skimming flow. However, for fish passage over the deflector, the Type I deflector (12.5 ft horizontal with lS-ft radius transition) can likely be adopted with little degradation in dissolved gas uptake. Loadings on the deflector were estimated with pressure measurements on the horizontal and vertical faces. Instantaneous cavitation pressures were measured on the vertical face of the deflector due to flow separation. Only minor cavitation damage has been observed at other spillway deflectors, and thus, significant damage is not expected. Pressure measurements on the stilling basin flow show potential uplift pressure as high as 3,300 lb/ft. If these pressures have a pathway beneath the stilling basin apron, significant uplift force could result, ultimately causing a catastrophic failure of the apron.

Book Spillway and Stilling Basin John Day Dam Columbia River Oregon and Washington Hydraulic Model Investigation

Download or read book Spillway and Stilling Basin John Day Dam Columbia River Oregon and Washington Hydraulic Model Investigation written by and published by . This book was released on 1974 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two sectional models were used to check performance of the proposed spillway for John Day Dam and to develop improvements if necessary. A three-bay section of the 20-bay spillway was studied in a 1:41.14-scale model. A two-bay section of the 17 low bays to be used during second-step construction was reproduced in a 1:24-scale model. Modifications of the crest piers to reduce the danger of cavitation during unusually large spillway flows were recommended. Discharge ratings in the three-bay model indicated that capacity of the spillway was slightly greater than computed for the design flow of 2,250,000 cfs. A 185-ft-long stilling basin at elev 114 performed as well as a 210-ft-long basin at elev 118. Three 10-ft-high baffle piers produced desired flow conditions in bay 2 of the stilling basin.
