Demonstration Erosion Control Project Monitoring Program, Fiscal Year 1992 Report. Volume 7: Appendix F. Model Study of Bendway Weirs as Bank Protection
Abstract
The purpose of monitoring the Demonstration Erosion Control (DEC) project is to evaluate and document watershed response to the implemented DEC project. Documentation of watershed responses to DEC Project features will allow the participating agencies a unique opportunity to determine the effectiveness of existing design guidance for erosion and. flood control in small watersheds. The monitoring program includes 11 technical areas: stream gaging, data collection and data management, hydraulic performance of structures, channel response, hydrology, upland watersheds, reservoir sedimentation, environmental aspects, bank stability, design tools, and technology transfer. This appendix discusses the bendway weir concept, which had been developed previously for application on the Mississippi River to eliminate shoaling problems for navigation in bendways, caused by the natural point bar deposition on the inside of bends encroaching into the navigation channel. From those previous investigations on navigation problems, it was learned that bendway weirs would not only widen the channel in a bend, but would also change the way water and sediment move through the bend.
