It sounds like you're referring to irrigation, where water is diverted by ditches and canals to make land more suitable for planting crops. Irrigation ditches can divert water from free-flowing rivers and streams or from reservoirs created by dams.
I think canals always have water and ditches only sometimes do
Pipes can carry more water than ditches and canals because they have a smoother interior surface which allows for higher flow rates. Additionally, pipes are more efficient in controlling the flow of water and reducing losses due to leakage and evaporation compared to ditches and canals.
