: An Explainer
The lower reaches of the Mississippi River are being hit by record floods, as detailed on our In Focus photography blog. While there are thousands of news stories about what's happening, I found myself wanting basic knowledge about how the Mississippi works now. It's such a complex hybrid human-natural system with a deep and complex history that it's hard to know where to start.
While Humans vs. The Mississippi was most elegantly laid out in John McPhee's stunning story "Atchafalaya," we found ourselves wishing for a simpler tech explainer (or companion piece). How is a levee built? What's a revetment? What does the crucial Old River Control Structure look like? This explainer is intended to delve into these issues.
