Outlet Structure for Meramec Lake, Meramec River, Missouri. Hydraulic Model Investigation.

Abstract

Model investigation of the outlet works for Meramec Lake was concerned with verification and improvement of the hydraulic performance of the intake structure, transition, conduit, stilling basin, and exit channel. Hydraulic performance of the original and revised outlet works with 22- and 14-ft-wide horseshoe-shaped conduits, respectively, was investigated by means of 1:40- and 1:25.5-scale models. Flow distirbution into the stilling basin was improved by providing a 38-ft-long horizontal apron immediately downstream of the 14-ft-wide conduit and placing the sidewalls 1 laterally in 16 longitudinally from the exit portal to the end sill. General discharge characteristics of the outlet works were defined as well as the minimum size and extent of stone protection required in the exit channel immediately downstream of the flared stilling basin.
