What are canals and why did the egyptians built them?

Canals are artificial waterways constructed to facilitate the movement of water for irrigation, transportation, and drainage. The ancient Egyptians built canals primarily to manage the annual flooding of the Nile River, allowing them to irrigate their crops and support agriculture. This system of canals helped to sustain their civilization by ensuring a reliable water supply for farming, which was essential for their economy and food production. Additionally, canals improved trade and communication between different regions of Egypt.
