Step 3
Way Explained/Described
Answer
Levees are natural or artificial embankments built along the banks of rivers to prevent overflow during periods of high discharge. They function by containing the river's flow within specific channels, reducing the risk of flooding in surrounding areas. The effectiveness of levees relies on routine maintenance and monitoring to address potential weaknesses that could lead to failure during extreme weather events.
Step 4
The Example Studied
Answer
A notable example of levee construction is the levee system along the Mississippi River in the United States. This system was developed in the 19th century to mitigate the frequent flooding that affected agricultural and urban areas. It has been instrumental in protecting cities like New Orleans from flooding, particularly during hurricane season.
