dc.description.abstractAbstract: The Morganza Floodway west of the Mississippi River was evaluated using a two-dimensional Adaptive Hydraulics Model. The study was conducted to develop a better understanding of how the area would flood for pre-2011 flood conditions. The hydraulic roughness values for the floodway were set for the pre-2011 flood conditions. The results from the model run with original tailwater rating curve from the 1950 model study produced gage readings in the floodway within +/- 1 foot of the measured values (U.S. River Commission 1950). However, water surface elevations produced from the model run with the revised tailwater rating curve values (which used discharge ratings from the physical model tests results) were even closer to the measured gage data (Maynord 2014). Results indicate that the model correctly simulates flow lines and inundation areas in the flood plain for the 2011 event. However, for other events the model should be updated with the appropriate elevation data and hydraulic roughness values.en_US
