Navigation Conditions, Suck Bend Reach, Chattahoochee River Alabama and Georgia. Hydraulic Model Investigation.

摘要

The Suck Bend Reach of the Chattahoochee River is in the upper end of Columbia Lock and Dam Pool about 1.5 miles downstream of the Walter F. George Lock and Dam. Suck Bend is essentially two adjacent and alternate bends in the form of a relatively flat 'S' curve. Shoaling that occurs in the bend during flood flows and at times during powerhouse operation has been a problem for navigation when there is little or no flow from upstream. A movable-bed model reproducing about 1.5 miles of the Chattahoochee River to an undistorted scale of 1:72, model-to-prototype, was used to develop plans that would eliminate or reduce shoaling sufficiently to permit uninterrupted navigation and to improve navigation conditions for larger tows through the bend and in the approach to the proposed State Highway 10 bridge.
