How would A river confluence cause flooding?

A river confluence can cause flooding if both rivers experience high flow rates or if one river is blocked by debris at the confluence, causing water to back up and overflow its banks. Additionally, the merging of the two rivers can create a bottleneck that slows down the flow of water, increasing the risk of flooding during heavy rain events.

Why did sumerians build dikes?

The Sumerians were the first to build an irrigation system. They learned how to use the floodings of the rivers to water their plants. They dug canals in which they could store the water and made gates (dikes) to protect their lands from flooding. When the river went back to its banks, the gates were closed and a lot of water remained in the canals. Without this knowkledge (and hard work) they just wouldn't have been able to live and farm in the very hot weather.


Why does flooding occur in North Dakota?

Flooding occurs in North Dakota due to large amounts of snowfall, not just in North Dakota but also in Montana. Add to that lots of rain, and the flooding increases. Since the land in North Dakota is flat, it takes the rivers longer to move the water and contributes to the flooding. Floods can occur when rivers and streams run over their banks. Although made to prevent floods from happening, dams and levees that experience breakage can also cause flooding. Earthen dams are susceptible to breakage when the soil loosens. Levees, used to hold back large bodies of water, are historically known to suffer from excessive water spilling over the top. States including North Dakota, South Dakota, Wisconsin, West Virginia, Minnesota, New Jersey and Oklahoma are prime suspects of when water overflows dams, levees, rivers and streams.
