dc.description.abstractThe Great Lakes and Mississippi River Interbasin Study (GLMRIS) is a U.S. Army Corps of Engineers study to evaluate methods of preventing the movement of aquatic nuisance species (ANS) movement between the Great Lakes and Mississippi River basins through aquatic connections. This report is an assemblage of ideas, preliminary hydraulic calculations, and numerical model evaluations that serve as part of the development of an ANS flushing system for Brandon Road Lock on the Illinois Waterway. Four flushing system designs and operations are presented. An analytical description of each lock flushing system design and numerical model results of those designs when applied to Brandon Road Lock are presented. Further, justifications and considerations of a physical model study of any lock flushing design that is chosen for construction are presented. This report is an overall commentary on design ideas and considerations for modeling the flushing rate of the lock chamber. The hydraulic details of lock flushing are outlined with the significant parameters of each lock flushing alternative highlighted. Numerical model results are presented to quantify the effectiveness of each lock flushing concept considered in this study.en_US
