Surges in the Intermediate Pool of Long Sault Canal, St. Lawrence River: Hydraulic Model Investigation
Abstract
Tests to investigate surges that could occur in the intermediate pool of' Long Sault Canal between Eisenhower and Grass River Locks through accidental failure of' the gates in the upstream lock were conducted on a fixed-bed model built to a horizontal scale of' 1 to 200 and a vertical scale of' 1 to 100. The test results showed that the maximum height of the surge above normal pool elevation would be 4.5 ft at the downstream (Grass River) lock when closing of the emergency lift gate of Eisenhower Lock was started 10 minutes after the miter gates failed and closure was completed in 19 additional minutes. For these conditions, the design height of the Grass River Lock walls is adequate to contain the surges produced. However, if water were prevented from flowing onto overbank areas adjacent to the canal, surges at Grass River lock would increase to 14.4 ft above normal pool elevation.
