Irrigation System

IRRIGATION SYSTEM The design equipment and technique of replenishing the soil water deficit by applying irrigation water is referred to as irrigation system. It is required due to following facts : 1. There should be minimum or no wastage of water. 2. It should be inexpensive and economically viable.

IRRIGATION SYSTEM ARE AS FOLLOWS :1.

CANAL SYSTEM : Here rivers supply water to canals. Canal is divided into sub canals and distributaries. Further field channels may be made.

2.TANKS : Tanks are small storage reservoirs, which store the run off of smaller catchments areas. Small dams are constructed below the higher elevation of the catchments

area.

In

the

tanks

outflows

regulated according to the water availability.

are

3.WELLS : These are made to use ground water. They are of two types i.e., dug wells and tube wells. In dug well, water accumulates due to available ground water table. From deeper areas of earth, tube wells can tap water. Here water is lifted by diesel or electricity operated water pumps. Continuous supply can be ensured by this system

4.RIVER VALLEY SYSTEM : In western Ghats of Karnataka and Kerala, many steep and narrow reverie valleys are present. Rainfall in these areas is present only for shorter period i.e., 3-4 months. Extra water shifts rivers in these months. In Rabi season no rainfall is there . On slopes, plants like coconuts, coffee, rubber are

grown. These all are perennial plants. In basement areas, single crop like rice is grown.

5.RIVER LIFT SYSTEM : In this system, water is directly drawn from rivers for irrigation purpose. This all is done in areas near to rivers and canals flow is insufficient.
