Floodwaters primarily originate from excessive rainfall, rapid snowmelt, or the overflow of rivers and lakes. They can also result from storm surges during hurricanes or tropical storms, as well as from dam or levee failures. Urbanization and poor land management can exacerbate flooding by increasing runoff and reducing natural drainage. Additionally, coastal areas may experience flooding from rising sea levels and tidal changes.
Allows floodplains to absorb floodwaters without harm to structures
A levee is formed by the natural deposition of sediment along the banks of a river during flood events. As floodwaters overflow the river's banks, they lose velocity and drop sediment, creating elevated ridges over time. Human intervention can also enhance levee formation through the construction of earthen or concrete barriers to manage floodwaters. These structures help protect adjacent land from inundation and can be reinforced through continuous sediment deposition or maintenance activities.

Levees were crucial to the Sumerians as they helped manage the flooding of the Tigris and Euphrates rivers, which could be both destructive and beneficial. By controlling floodwaters, levees protected agricultural land, ensuring stable crop production and supporting the growth of Sumerian city-states. This flood management system also facilitated irrigation, enhancing agricultural efficiency and contributing to the development of their economy and society. Overall, levees played a vital role in sustaining Sumerian civilization.
The plural of floodwater is floodwaters:"The floodwaters had reached the third floor windows and continued to rise."

Eventually, most floodwaters find their way to the seas and oceans. Some of the floodwaters replenish underground aquifers and supplies, such as the Great Artesian basin in Australia.

Ancient Mesopotamia is known for developing sophisticated systems for controlling and using floodwaters. The government in Mesopotamia, particularly in the city-states of Sumer, took on the responsibility of managing irrigation canals, building levees, and utilizing floodwaters for agriculture through a system of organized labor and community cooperation.
