Lower Mississippi River Environmental Program. Report 13. Preliminary Environmental Design Considerations Associated with Articulated Concrete Mattress Revetments along the Lower Mississippi River

摘要

Preliminary environmental design considerations are described for Articulated Concrete Mattress (ACM) revetments along the Lower Mississippi River. These considerations were developed for the Mississippi River Commission for possible use and maintenance of ACM revetments within the Mississippi River and Tributaries Project. The environmental considerations are preliminary inasmuch as they would require additional field testing and engineering and cost and evaluation prior to large-scale implementation. Environmental measures discussed include modification to the upper surfaces of ACM blocks, stone and wood habitat structures, creation or expansion of eddies, artificial spawning devices, and management of vegetation for fish, macroinvertebrates, and wildlife. A review of the literature relating to environmental values of ACM revetments is presented. (FR)
