Model-Prototype Conformity: Spillway Coefficients, Norris Dam

Abstract

The determination of discharge coefficients for the dam spillway crest gates 8a is described in this paper. Actual coefficients calculated for the gates from records of their performance during the flood of January and February, 1937, are compared with the coefficients predicted from tests made on a 1 : 72 scale model by the Bureau of Reclamation. This comparison indicates that the coefficients predicted by the model average 3.9% larger than those actually measured on the dam during this period.
