they can easy break or fail when the water flow is very fast and strong
A levee is a high wide wall built along the banks of a river to prevent flooding by containing the water within the river channel.
A levee is a bank of earth that keeps out water by providing a barrier to prevent flooding. It is commonly used along rivers and coastlines to protect communities and land areas from water intrusion.
A high bank of soil along a river to prevent flooding is called a levee. Levees are built to contain the river within its channel and prevent water from flowing into surrounding areas during periods of high water levels. They help reduce the risk of flooding in adjacent communities.
When levees are built along a section of the river, the water will rise higher, then the water will flood in a different place that did not flood before the levee was built. Many natural flood plains have been cut off by levees. That is why cities flood more because the high water is going to go somewhere. Levees don't stop high water. They just cause it to move somewhere else.
it provides a benefit to the entire community by reducing the risk of flooding for all residents, regardless of whether they directly contribute to its upkeep. It is non-excludable and non-rivalrous, meaning that one person's use of the levee does not diminish its effectiveness for others.

to help control flooding
So long as a levee holds and is not overtopped, water cannot cross from one side to the other.
Levees prevent flooding from rivers that overflow their banks.

It keeps rising water inside stream channels.
If the level of the river rises, the levee gives the river unnaturally high banks thus preventing flooding in the community which has them and virtually guaranteeing flooding in the next community downstream.

Nope... a delta - is the natural mouth of a river. A levee is an artificial bank built up to prevent flooding of low-lying areas.
The direct cause of flooding was the failure of the levee along that canal.
It pulls water downstream before it can flood.
