Effects of Overbank Vegetation on Mississippi River Stages in the St. Louis-to-Thebes Reach.
Abstract
This model investigation was conducted on the St. Louis-to-Commerce Reach of the Mississippi Basin Model to determine stages to be expected along the Mississippi River with varying amounts of overbank vegetation between the river and its bluff line or levee. The data obtained from this study will be used to determine the sensitivity of the flow regime to land-use changes riverside of the levees. The Mississippi Basin Model is a fixed-bed model of the Mississippi River and its tributary system built to a horizontal scale of 1:2000 and a vertical scale of 1:100. Prior to conducting this study, the model was adjusted to reproduce the 1973 flood. The overbank roughness was placed on the model at locations where aerial photographs showed timber to exist in the prototype in 1973. The density of this roughness was adjusted to reproduce prototype stages for the 1973 flood. Four series of tests were conducted in this study. Each series simulated a different overbank vegetation condition between the river and its bluff line.
