Katrina and the River

“The Mississippi River will always have its own way; no engineering skill can persuade it to do otherwise,” said Mark Twain. In this, our final episode marking the 20th anniversary of Hurricane Katrina, we consider how efforts to control the Mighty Mississippi – a river engineered from its Minnesota headwaters to its Gulf Coast outlet – have responded to the devastating storm, and how New Orleans’ relationship to the river has changed. Can the city keep up with the pressure that climate change is putting on this engineered system, or is retreat the only viable response? Plus, a wetland recovery project that aims to bolster protection from hurricanes and flooding in the Lower Ninth Ward.
