Description: Technical memorandum
Synopsis: This memorandum constitutes the final report on the model study performed at the U. S. Waterways Experiment Station of the spillway for the Berlin Dam, Mahoning River (see plate 1) . The dam will be composed of a concrete-gravity spillway section in and adjacent to the stream bed with rolled earth embankments connecting the ends of the spillway to high natural ground on both sides of the valley (see plates 2 and 3). The spillway will be composed of a gated section in the stream bed area flanked by an uncontrolled spillway section on each side and is designed to pass a maximum discharge of 79,000 cfs. The general purpose of the study was to investigate the hydraulic performance of the spillway and to develop an economical stilling- basin design. All tests were conducted on a model built to the linear-scale ratio, model to prototype, of 1 to 48. Reproduced in the model were 720 ft of the approach area, a portion of the earth embankment, the spillway proper, the stilling basin, and about 1300 ft of the exit channel.
