Model Study Results, Copeland Cut Reach, St. Lawrence River. Phase 1. Numerical Model Investigation.
Abstract
Cross currents in the Copeland Cut Reach of the Wiley-Dondero Canal make navigation difficult during periods of high flow with accompanying low water levels. The problem area is located in Lake St. Lawrence approximately 3 miles west of Eisenhower Lock. A TABS-2 numerical model reproducing a portion of Lake St. Lawrence from Wilson-Hill-Ault Islands downstream to Eisenhower Lock, Long Sault Spillway Dam, and Moses-Sanders Power Dam was used to investigate current patterns in the problem area and the distribution of flows through the system. The model was used to evaluate plans for reducing the magnitude of the cross currents by altering the distribution of flows through the system. The results of this investigation showed that significant reductions in cross current magnitude could be achieved by closure of a river channel downstream of the problem area. A physical model study has been proposed to refine these plans. The numerical model will be used to generate boundary conditions for the physical model. (rrh)
