Abstract

In arid and semiarid areas, rainfall is markedly variable in magnitude, time of occurrence, and spatial distribution. Irrigation is required to meet the demand of agriculture, but surface water supplies are also characterized as scarce and unreliable. Consequently, farmers consider it necessary to create a dependable water supply, which is adequate and in a desired location. This management option has spurred farmers to develop the technology of irrigation wells. History started with the development of irrigation wells to be used for lifting water from rivers (surface water), surface storage (rainfall), and subsurface dug holes (underground water). The discharge rates of such irrigation wells depend on the capacity of the lifting devices. As pumps were introduced, a boom in another kind of irrigation well occurred to exploit underground water for irrigated agriculture. Promising technologies of irrigation wells include tube wells, skimming wells, dug wells, and radial wells. The discharge rates of these irrigation wells depend on the capacity of the lifting devices and also on the hydrogeologic characteristics of the aquifer.
