Book excerpt: The spillway for Clarence Cannon Dam, which is to be subjected to discharges as large as 268,000 cfs, was studied on a 1:50-scale comprehensive model to determine flow conditions in the approach and exit channels and performance of various elements of the structure. The withdrawal characteristics of the original design water-quality weir were unsatisfactory and subsequent modifications were developed to obtain the desired withdrawal characteristics without affecting the capacity of the spillway. Simulated pumpback operations indicated that the proposed pumped storage scheme of power generation will not produce any material internal mixing or destratification of the reservoir. The right and left abutments were modified to reduce drawdown and improve distribution of flow entering the stilling basin. The baffle piers were relocated to improve energy dissipation in the stilling basin. Stilling basin training wall heights were reduced downstream of the baffle piers without impairing hydraulic jump action or exit channel velocity distribution. Dynamic shear and moment on each of the six monoliths of the divider wall between the stilling basin and powerhouse tailrace were measured by means of electronic force cells. The size and extent of exit channel protection required downstream of the spillway were also determined. (Author).
