Full Answer

How did the Mississippi River course has changed over time?

Through a natural process known as avulsion or delta switching, the lower Mississippi River has shifted its final course to the mouth of the Gulf of Mexico every thousand years or so. This occurs because the deposits of silt and sediment begin to clog its channel, raising the river's level and causing it to eventually find a steeper, more direct route to the Gulf of Mexico.

What makes a river change its course?

Due to constant deposition of river sediments on the slower side and the vast amount of erosion that takes place on the faster side. This process keeps on continuing till the curves get sharpened, so that river cuts through the curve and forms another path and thus river changes its course.

Do rivers ever change course?

All rivers naturally change their path over time, but this one forms meanders (the technical name for these curves) at an especially fast rate, due to the speed of the water, the amount of sediment in it, and the surrounding landscape.

How long has the Mississippi River changed course?

The Mississippi River has changed course to the Gulf every thousand years or so for about the last 10,000 years. Gravity finds a shorter, steeper path to the Gulf when sediments deposited by the river make the old path higher and flatter. It’s ready to change course again.

What is the effect of floods on the Mississippi River?

The higher the hill, the greater the “head” or force driving the flow. Floods on the Mississippi raise the water level inside the levees and increase this force. Floods are becoming more frequent, longer, and higher — even though average annual rainfall in the Mississippi drainage basin has been almost flat since 1940.
