The model, located in Memphis, spans over 200 acres and was used by the U.S. Army Corps of Engineers to study flood control and river navigation from 1943 to 1973.
The model replicates the entire Mississippi River Basin at a scale of 1:1000 horizontally and 1:100 vertically, allowing for precise simulations of river conditions.
In 1993, the American Society of Civil Engineers recognized the model for its significant contributions to engineering and flood control.
During World War II, the model was classified due to its strategic importance in planning military logistics and infrastructure.
After its decommissioning, the model was transformed into a park where visitors can walk along the paths that trace the river's course.
