Qualitative Erosion and Sedimentation Investigation Maline Creek, City and County of St. Louis, Missouri.
Abstract
Flooding of Maline Creek in and around St. Louis, Missouri has been a problem. In an effort to provide significant flood damage mitigation, increase outdoor recreation opportunities, and enhance the watershed's environmental quality, the U.S. Army Corps of Engineers, St. Louis District has evaluated potential improvement alternatives for the creek. A selected plan for improvement was identified in a 1980 survey report (COE). The recommended plan of improvement consists of the following features: (1) 8 dry detention sites, (2) 3.29 miles of channel widening and straightening, (3) 5.05 miles of low level floods, (4) 3.31 miles of low levels levees, (5) 91 acres of clearing, (6) 5 bridge replacements, (7) 2 bridge improvements, (8) 18 aquatic habitat structures, (9) 5 fish ponds, (10) 384 acres of open space adjacent to detection basins plus 474 acres along the stream corridor, and (11) 10 miles of environmental/recreational trails. The sediment transport characteristics of Maline Creek, were qualitatively evaluated and the effect of the proposed improvements on sediment transport in the creek was assessed. Generalized solutions to potential erosion and sedimentation problems are suggested and a literature review of erosion and sedimentation in urban areas is presented. Particular emphasis of the literature review was placed on erosion and sedimentation of loess soils since they are common to the Maline Creek watershed.
