Navigation Study at the Approach to Lock and Dam 24, Upper Mississippi River. Hydraulic Micro Model Investigation. Volume 1
Abstract
A sedimentation and navigation study of the Mississippi River, between River Miles 271 and 277.5 was conducted to study and solve the outdraft problem at the downbound approach to Lock and Dam 24 in Clarksville, Missouri. Outdraft has been a severe problem at Lock 24 since operation began. The outdraft conditions cause transportation delays and accidents, which may cause damage to the miter or tainter gates as well as injuries or loss of life. A physical hydraulic micro model was used to access 30 structural design alternatives to alleviate or eliminate the outdraft conditions. The study recommended constructing four bendway weirs upstream of the lock chamber and extending dike 274.OR. Model tests indicate that outdraft was significantly reduced as a result of these remedial measures. Construction sequencing of this recommended plan was also studied through model testing.
