Lower Mississippi River Environmental Program. Report 4. Environmental Design Considerations for Main Stem Levee Borrow Areas Along the Lower Mississippi River

摘要

Environmentally important physical features of main stem levee borrow areas along the Lower Mississippi River are identified and presented as design considerations. These design considerations were developed for the Mississippi River Commission for possible use in design and construction of the Mississippi River levees portion of the Mississippi River and Tributaries Project. Routine, relatively inexpensive environmental measures and more complex, costly measures are identified and discussed. Environmental measures discussed include borrow pit size, depth, shape, and vegetation and cover for both fish and wildlife. A review of the literature relating to the ecological characteristics of borrow pits and similar water bodies is presented. (Author)
