ancient egyptains used the nilometer to measure the water in the nile river
The nilometer was invented by the ancient Egyptians. It was used to measure the level of the Nile River in order to predict flooding and ensure successful agricultural planning.
It was measured with a nilometer.
The nilometer measured the rise of the Nile River during floods. Knowing where the Nile River was going to flood was crucial for knowing where to plant crops and where to build houses.
A structure built in the Nile river to measure water levels.
The egyptians invented the Nilometer to measure the hight of the River Nile. The reason the Egyptians measured the hight was to predict what the harvest would be like; 8.5 meters=hunger 9.0 meters=suffering 9.5 meters=happiness 10.0 meters=security 12.0 meters=disaster

They were sets of steps, measuring how high the water reached. There was also a column in the middle where the numbers were.
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.

One example of how technology helped the Egyptions understand the Nile is the nilometor. The nilometer helped the Egyptions measure how much of the Nile river flooded.
They got their education by secretly learning it if their master didn't allowed because it was illegal. Sometimes, their masters tought the slave even though it was against the law. By secretly learning it, they could learn it off another slave or steal a book and educate themselves.
