Sedimentation and Navigation Study of the Mississippi River at Semo Port, Miles 49 to 47. Hydraulic Micro Model Investigation. Volume 1 of 1

摘要

A sedimentation study of the Mississippi River at SEMO Port, between Miles 49 and 47, was conducted by the U.S. Army Corps of Engineers, St. Louis District. The study was undertaken in order to examine depositional trends experienced within Southeast Missouri Port and determine, if possible, remedial measures to minimize this deposition from various structural alternatives. Using a micro model with a scale of 1 inch = 300 feet horizontal and 1 inch = 100 feet vertical, the study determined that deposition was a result of the settlement of fine materials from water entering the port during high flow events. An extension of an existing berm surrounding the port was proposed to minimize water entering the port during high flow events. In addition, a series of Bendway Weirs in the adjacent Mississippi River navigation channel were proposed to minimize bed load contribution at the port entrance.
