Egyptians were clever. They had rivers, water and advanced water-management technology.

The shaduf, which is a hand-operated lever with a bucket, to lift water from rivers and canals for irrigation.

The Nile River annually flooded which was monitored because it determined agricultural success.

As well, the Nile served as a transportation route. Huge stone blocks transported through and evidence suggests that canals and harbours were built near some pyramid complexes to help move materials closer to construction sites.

Clever people. Not as advanced as the Romans but they had technology and prospered for a long while.
