Filling and Emptying System, New Poe Lock, St. Marys River, Sault Ste. Marie, Michigan.

Abstract

The lock hydraulic system was tested in a 1:25-scale model to determine (a) adequacy of intake and discharge manifold designs; (b) maximum permissible lock filling and emptying rates with turbulence and hawser stresses within safe limit; and (c) best location, number, and spacing of bottom laterals. The original design intake manifolds and upstream pier nose shape were revised to reduce vortex tendencies at the intake and improve flow distribution. Tests revealed that the bottom split-lateral system (i.e. two groups of six laterals each) of filling and emptying the lock was satisfactory. (Author)
