Surface irrigation, also known as gravity irrigation, is the oldest form of irrigation and has been in use for thousands of years. In surface (furrow, flood, or level basin) irrigation systems, water moves across the surface of agricultural lands, in order to wet it and infiltrate into the soil. Water moves by following gravity or the slope of ...
A tank cascade is a system of irrigation tanks in single or multiple chains where water from a higher tank flows into lower tanks. Examples of tank cascades include Sri Lanka's tank cascade system, [6] the Indian city of Bangalore's cascading lakes in the Varthur lake series, [7] and the Indian city of Madurai's Vandiyur tank cascade system.

A small center pivot system from beginning to end. Irrigation equipment can also be configured to move in a straight line, where it is termed a lateral move, linear move, wheel move or side-roll irrigation system. [11] [12] In these systems the water is supplied by an irrigation channel running the length of the field. The channel is positioned ...
In sprinkler irrigation, water is piped to one or more central locations within the field and distributed by overhead high-pressure water devices. Micro-irrigation is a system that distributes water under low pressure through a piped network and applies it as a small discharge to each plant. Micro-irrigation uses less pressure and water flow ...
The use of sprinkler irrigation and micro-irrigation systems decreases the risk of waterlogging and erosion. [34] Where practicable, using treated wastewater makes more water available to other users [ 34 ] Maintaining flood flows downstream of the dams can ensure that an adequate area is flooded each year, supporting, amongst other objectives ...
It is the largest water reclamation project in the United States, supplying irrigation water to over 670,000 acres (2,700 km 2) of the 1,100,000 acres (4,500 km 2) large project area, all of which was originally intended to be supplied and is still classified irrigable and open for the possible enlargement of the system. Water pumped from the ...
