What would Egypt be like if the Nile never flooded?

Due to the fact that due to the flooding of the Nile, most of the land was irrigated, this area was almost completely self-sufficient with food.
If such spills did not occur, then the area of land suitable for farming was less, as a result of this, the amount of the harvest was less, and therefore the population was poorer.
These territories would be practically no different from the desert.
As a result, the existence of the population in this area was limited to the coastal areas of the river.
