NEED HELP ASAP!!!
Levees are structures built around rivers to control and prevent flooding. In Louisiana, massive levees have been built around the Mississippi River. Prior to the levees being built, seasonal floods would deposit sediment rich in nutrients throughout the wetlands and floodplains in Louisiana. Now, the sediment is carried out to sea, and areas around the levees are rarely flooded.
What is a solution that reduces the impact of levees on the environment in Louisiana?
A
Redirect water in the continental U.S. to other rivers and coasts.
B
Increase the height of the levee's walls to prevent all possible flooding.
C
Divert, or distribute, river sediment from the state's coastal areas into wetlands.
D
Build levees that go further upstream on the Mississippi River.
