Ancient Egyptians needed the floods to irrigate crops. Egyptians would measure the water with a nilometer so people upstream would be aware of how much water was coming.
Regarding Egypt, they use a device they called a 'Nilometer'. This measured the water levels of the Nile and took various forms, from a simply pillar to a complex structure. They would be marked-off in 'cubits' which equalled about half a meter. It was reckoned that if the water level did not reach the mark of 16 then there would be drought and famine.
