Irrigation systems such as irrigation ditches, channels and canals artificially supply dry land with water.
A river is a system which supplies dry land with water naturally, not artificially.
Irrigation
Irrigation in its most common definition is the watering system used to grow crops.Irrigation is defined as the process of artificially supplying water to the soil for raising crops. It is the engineering of controlling and harnessing the various natural source of water by the construction of dams and reservoirs.Irrigation is an artificial application of water to the soil. It is usually used to assist the growing of crops in dry areas and during periods of inadequate rainfall.
A watershed is not a building, it is an area of land that contributes run off to a given lake, stream, river or other body of water. It's purpose is to supply water to the water body. (From Ask.com)
land
On land fresh, on sailboats salt water.
A drainage channel is designed to remove excess water from an area, such as rainwater or wastewater. It is typically sloped to allow water to flow away from the area and may have a grate or cover to prevent debris from entering. An irrigation channel, on the other hand, is designed to bring water to an area for the purpose of watering plants or crops. It may be lined with concrete or other materials to prevent erosion and may have gates or valves to control the flow of water.
Irregation
Irrigation is a system that was needed to transport water to a section of land that is being used to grow crops. This system is controlled because there is such a thing as too much water and too little: Too much and the plants will drown, too little and the plants will not grow or be stunted..
If land was not regulated, then there could be more pollution. Polluted areas would cause the water supply to be unusable and undrinkable if runoff from chemical sources enter into the supply.

The water cycle renews the supply of fresh water on land.
It made it easier to supply water to land
Primarily over land and water supply.
Because it is the land area that supplies water to a river system :)

Land cuts off the supply of water vapor to the typhoon that keeps it going.
