Abstract : The Red River Waterway provides for the development of a 9-ft-deep by 200-ft-wide navigation channel from Lake of Pines near Dangerfield, Texas, to Old River. The lower reach of the Red River with its flat slopes and narrow bends of short radii transverses the flood plain of the Mississippi River. A movable-bed model, reproducing about 4.7 miles of the Red River and a short section of the Black River to a horizontal scale of 1:120 and a vertical scale of 1:80, was used to provide an indication of the amount of maintenance dredging that would be required to: (a) maintain a navigation channel from Lock and Dam 1 to Old River; (b) develop a system of channel training structures to minimize the required dredging; and 9c) determine the ultimate channel section to be expected in Lorran Lake cutoff, a cutoff proposed just upstream of the mouth of the Black River. Results included: 1) The proposed overall channel was too wide to maintain a navigation channel of adequate width and depth above the Black River. 2) Development of an adequate navigation channel in the test reach would require a reduction in the width of the overall channel. This can be obtained with dikes or by moving the banks closer together and revetting them. 3) Structures would be require on the left downstream of the Black River to develop an adequate channel along an alignment suitable for navigation. Keywords: Hydraulic models.
