Stream Channel Stability. Appendix A. Evaluation of Streambank Erosion Control Demonstration Projects in the Bluff Line Streams of Northwest Mississippi,

This report presents an evaluation of some of the most commonly used types of channel bed and bank revetments used on bluff line streams of the Yazoo Basin. Specific revetment techniques used on Goodwin Creek, Johnson Creek, Hotophia Creek, Tillatoba Creek and Perry Creek watersheds were used to illustrate successes and failures. A complete section is devoted to each of these watersheds and includes the watershed description, geology, soils and evaluation of performance of selected revetment techniques. Special attention is given in this report to a newly developed, low-cost, grade control structure. During this project, twelve of these grade-control structures were built and their performance was evaluated for this report. Generalized engineering design criteria for these low-drop, grade-control structures are given in Appendix B AD-A101 387 of the general report.
