Spillway for Alum Creek Dam, Alum Creek, Ohio: Hydraulic Model Investigation.
Abstract
Tests were conducted on a 1:60-scale model of the Alum Creek Dam spillway to determine flow conditions in the spillway approach channel, discharge characteristics of the spillway, stilling basin performance, and flow conditions in the outlet channel. The spillway consisted of an ogee crest with three 34-ft-wide by 25-ft-high tainter gates, a spillway chute, and a hydraulic-jump type stilling basin. Flow conditions in the curved approach channel to the spillway were satisfactory for the expected discharges. The discharge capacity of the original design was slightly greater than expected. Discharge coefficients and pier and abutment contraction coefficients were determined from model data. The original design stilling basin did not perform satisfactorily. However, a satisfactory and more economical design was developed. Velocities of flow were measured in critical areas of the approach and outlet channels for use in design of riprap protection.
