The Aswan High Dam completed in 1970.
The Aswan Dam was built in 1956 to control the Nile River floods and produce electricity. Before the dams were built, the Nile River flooded every year during late summer, when water flowed down the valley from its East African drainage basin.
In ancient Mesopotamia, two key methods used to control annual floods were the construction of levees and the development of an extensive irrigation system. Levees, or raised banks, were built along riverbanks to prevent overflow during peak flood seasons. Additionally, the irrigation system allowed for the diversion of river water to agricultural fields, managing both the water supply and mitigating flood risks while ensuring reliable crop production.
Dams are usually built were there are droughts or floods because damns can control the flow of water to prevent floods from happening and store water in case a drought affects a local town, village or city.
The Aswan high dam is important because it controls the Niles annual floods, which previously flood settlements bordering the river, and generates electricity and makes the Nile easier to control.
They built these walls called Chounts and that pretected the flooding but three times the Chount did not work

They usually build canals that brought water directly to the crops or built up walls around there cities to protect from strong unknown floods.
Mohenjo-Daro was influenced by geography by having all of it planned .Also, they wanted to be protected from incoming floods and the city was built above the ground level.
A dam is a structure built across a river to control the flow of water. It helps regulate water levels, generate hydroelectric power, and provide water for irrigation and drinking. Dams can also prevent floods and create reservoirs for recreational activities.
No, in fact, dams would collapse or crack in an event of an earthquake. Dams are built more to control floods, especially if they occur frequently and do destructive damage, just like why the Three Gorges Dam was built.
Kane's Bridge at Fairfield in Victoria was built in 1929 and rebuilt after floods in 1935.
