Mississippi River Basin Model: A Miniature Giant

Explore a unique piece of engineering history: the Mississippi River Basin Model, a massive, open-air replica of the Mississippi River watershed.

4.1

The Mississippi River Basin Model, located in Jackson, Mississippi, is a large-scale hydraulic model of the Mississippi River basin. Built between 1943 and 1966, the 200-acre model was used to simulate flood conditions and test the effects of flood control measures before the advent of computer modeling. Today, it sits derelict but open to the public in Buddy Butts Park, offering a unique glimpse into engineering history.

A brief summary to Mississippi River Basin Model

Local tips

  • Wear comfortable shoes, as you'll be walking on uneven terrain while exploring the model.
  • Bring water and snacks, especially during hot weather, as there are limited facilities on-site.
  • Be aware that the model is largely unmaintained and can be overgrown, so dress accordingly.

The Mississippi River Basin Model stands as a testament to American engineering ingenuity. Constructed between 1943 and 1966, this massive hydraulic model was designed to replicate the entire Mississippi River basin, covering an impressive 200 acres. The model was a crucial tool for the U.S. Army Corps of Engineers, allowing them to simulate flood conditions and evaluate the impact of various flood control measures. Before the age of advanced computer modeling, the physical model offered a tangible way to understand the complex dynamics of the river system. The model incorporates over 15,000 miles of river channels and tributaries, representing 41% of the land area of the United States. The horizontal scale was 1:2000, and the vertical scale was 1:100. This difference in scale allowed for better simulation of turbulence and surface tension. Walking around the site, one can see the concrete panels shaped to represent the topography of the river basin, including the Appalachian Mountains raised 20 feet and the Rocky Mountains raised 50 feet. The model was actively used from 1949 until 1973, after which computer models became more prevalent. In 1993, the site was handed over to the city of Jackson and designated as a Mississippi Landmark. Today, the model is located within Buddy Butts Park and is open to the public, though it has fallen into disrepair and is overgrown with vegetation. Despite its derelict state, the Mississippi River Basin Model remains a fascinating historical landmark and a reminder of the innovative approaches once used to manage one of the world's largest river systems.
