Simulations of Floodflows in the Magby Creek Flood Plain Near Old Mill Road atColumbus, Mississippi

摘要

This report discusses the results of a study in which a two-dimensional finite-element surface-water model was used to (1) determine the effects of the newly constructed U.S. Highway 82 and the newly constructed pond levees on water-surface elevations and the flows in the Magby Creek flood plain that approach Lehmberg Road, and (2) determine the effects of a hypothetical floodflow diversion levee on water-surface elevations and the flows in the Magby Creek flood plain that approach Lehmberg Road. The report also discusses the selection of an appropriate model as well as the general theory and requirements of the selected model and the calibration strategy involved in the modeling process.
