The sea level around Mississippi is up to 7 inches higher than it was in 1978. This increase is mostly due to Mississippi’s sinking land, and it’s causing major issues. Coastal communities, such as the ones along the Mississippi Sound, are protected by barrier islands that are eroding from sea level rise.

Is the Mississippi River getting deeper?

Is the Mississippi Delta disappearing?
The Mississippi River Delta and coastal Louisiana lands are disappearing at an alarming rate: every 100 minutes, a football field of wetlands vanishes into open water. Louisiana has now lost more than 2,000 square miles of land since the 1930s, which equates to an area about the size of Delaware.
Why is the Mississippi River disappearing?
The causes of coastal erosion are elaborately interlinked — simplistically, they break down to sediment deficiency and saltwater intrusion.This subsidence, coupled with the deficiency of sediment, has made the Mississippi Delta region is the fastest-disappearing land on the planet.
Is the Mississippi getting smaller?

Why is Mississippi Delta so large?
Time, weather, and human intervention have all shaped the Mississippi Delta in Louisiana, a giant bird’s foot shape protruding into the Gulf of Mexico. The Mississippi River deposits sediment into the ocean, and over 25 years, NASA Landsat satellites observed changes in the delta’s shape.
Why is the Mississippi Delta so important?
The delta of the Mississippi River is an impressive area that has built up over millions of years. The sediment that the river carries to its end has created fertile soil and waterways that are very important for growing crops and shipping goods all over the world.
Is the Mississippi River delta growing?
The lack of growth in the Mississippi River delta, on a large scale, is as much a coast-wide problem as a basin problem. This source of ample fresh water and sediment, which shaped the Louisiana coast as we know it, is no longer producing a net gain in coastal wetlands, placing the entire Louisiana coast at risk.
Why is the Louisiana coast disappearing?
A lattice work of marsh and canals, the Louisiana coastline, is vanishing. A mixture of saltwater intrusion and sinking land has contributed to one of the fastest disappearing places on the planet, and an existential threat to the state itself.
Is Louisiana washing away?
Louisiana is losing its coast faster than any other place in the world. As land disappears and the water creeps inland, ancient archaeology sites are washing away.Officials are trying to rebuild those marshes and the wetlands, but much of the coast can’t be saved. This makes Louisiana’s history an unwitting victim.
