In this method water flows and spreads over the surface of the earth. Varied amounts of water are allowed in the fields at different times. Therefore, the flow of water under surface irrigation comes under unstable flow. As a result, it is very difficult to understand the hydraulic system of surface irrigation. However, an adequate and efficient surface irrigation method can be adopted after taking into consideration various factors involved in the surface irrigation hydraulic system.
Irrigation is the method in which a controlled amount of water is supplied to the plants at regular intervals for agriculture. It is used to help in the cultivation of agricultural crops, the maintenance of landscapes and the revegetation of disturbed soils in dry areas and during periods of insufficient rains. In addition, irrigation also has other uses in crop production, which include protecting plants against frost, suppressing weed growth in grain fields and preventing soil consolidation. On the contrary, agriculture that is based only on direct precipitation is known as rainfed or rainfed agriculture.
Irrigation systems are also used for dust suppression, wastewater disposal and mining. Irrigation is often studied along with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area.
Irrigation has been a central feature of agriculture for over 5,000 years and is the product of many cultures. Historically, it was the basis for economies and societies across the globe, from southwestern Asia to the United States.
