After dodging the bullet with the short-lived Hurricane Barry, we analyze the difference between freshwater flooding and salt water flooding and how aspects of those two different types of flooding can have different impacts on your landscapes.

The commercial fishing industry on the Gulf Coast has seen two major disasters in the last 15 years: Hurricane Katrina and the BP oil spill. Now, some fear we’re on the cusp of a third. The culprit: historic flooding from the Mississippi River.

If you live in a city it’s easy to think of Louisiana’s coastal land loss problem as out-of-sight, out-of-mind. But every day the coast is creeping closer and closer to New Orleans, and as sea level rise, more extreme storms and a deteriorating coast bring more flooding, some city-dwellers are trying to adapt to the changes.

Towns along the Upper Mississippi River are dealing with some of the worst flooding they’ve ever seen. Busted levees. Flooded downtowns. What does that mean for us in Louisiana? When should we be concerned, and when should we not be?

The Army Corps of Engineers expects to open the Bonnet Carre Spillway Friday afternoon.

Located upriver from New Orleans, the Bonnet Carre Spillway acts as a release valve for the Mississippi River. When the water reaches a flow of 1.25 million cubic feet per second, the Corps opens the spillway to divert some of that water into Lake Pontchartrain.

Scores of coastal research labs around the U.S. are helping communities plan for sea level rise. But now many are starting to flood themselves, creating a dilemma: stay by the coast and endure expensive flooding, or move inland, to higher ground, but away from their subject of study.

The Louisiana Universities Marine Consortium lab is located along the state's fragile coast, about 80 miles southwest of New Orleans. The giant X-shaped building is at the end of a gravel road, surrounded by open water and grassy marshes.

It’s been almost exactly one year since record-breaking rains flooded much of the city, and the city’s pumping and drainage system couldn’t keep up. Later it was revealed that many of the Sewerage and Water Board pumps and turbines weren’t working. Sewerage and Water Board officials say since then they've made $82 million in repairs, and today, the pumping and drainage system is in much better shape.

The best guesstimates of science show Hurricane Harvey headed toward Texas, but just in case…

“I have signed a statewide emergency declaration in preparation for Hurricane Harvey and its impacts on Louisiana,” Governor John Bel Edwards announced Thursday afternoon.


Since rainfall blanketed southeast Louisiana in August 2016, residents have wondered how the state can protect its people from future floods. Answering that question begins with understanding the geography we live in.
