- Water - for drinking, for animals and for daily use.
- Fertile soil - rivers deposit alluvial soil on their plains, which gives good crops.
- Irrigation - river water could be led into fields through canals and ditches.
- Surplus food - good harvests meant extra food, which freed people for crafts, trade and ruling.
- Transport and trade - boats could carry goods far more easily than carts on land.
- Settlement - because all of this was in one place, people could stay put and build permanent cities.
