Why did farmers in ancient Egypt use irrigation techniques?

Canals. The yearly inundation of the Nile was essential to Egyptian life, but irrigation canals were necessary to carry water to outlying farms & villages as well as to maintain even saturation of crops near the river. hope this helps bless you please mark brainiest if dont thats ok give it to the other one :)

it was on the rise and doing very well and would continue to do well until the great depression from 1929-1939
