The Mississippi River is one of the most iconic symbols of the United States, winding wide and mighty past major cities, tributaries and marshes, and all the way down to the Gulf of Mexico. Its path and route are constantly changing, due to a variety of factors, both manmade and natural. Learning more about how the Mississippi River changes course is important for understanding more about this ecosystem and its potential impact on our environment and landscape.<\/p>\n

Geological Processes<\/h2>\n

Geological processes, such as erosion and sedimentation, heavily influence changes in the Mississippi River. Erosion is the natural removal of land, usually through the water flow of a river. When erosion occurs, the river can gain strength and can develop new channels, altering its course. Sedimentation, on the other hand, is the deposition of sediment along the river’s banks, which can result in an increase in the water’s depth and width. As it creates new channels, the river also alters its route, changing where it travels and how it interacts with its surroundings.<\/p>\n

Human Impacts<\/h2>\n

Humans also impact the course of the Mississippi River through dam-building, land development, and deforestation. As rivers flow, they follow the shortest course and the least resistance. This can mean that a human-built dam can cause rivers to divert and reroute. Additionally, when humans develop land and pave streets, they create additional sources of water runoff, which can increase erosion in the environment and lead to channel shifts for the river. Deforestation and agriculture can also have an impact on the course of the river by eliminating plants near the river’s banks, which can reduce the amount of sediment that is held back by those plants.<\/p>\n

Floods and Storms<\/h2>\n

The Mississippi River changes course due to flooding and storms as well. During heavy rains, water from the Mississippi can overfill its banks and overflow into nearby creeks or streams, which can temporarily divert the river’s course. Additionally, severe storms, such as hurricanes and tornadoes, can cause severe flooding in certain areas of the Mississippi, forcing the river to take a new route. <\/p>\n
