A mathematical approach for sprinkler irrigation drop distribution on soil surface

Abstract

The objectives of this study were to develop an equation and derive equation for different boundary conditions of sprinkler irrigation drop falling and to stop runoff from soil surface. Irrigation scheduling is the process related to when, how much water to apply to a soil. The irrigation method concerns how that desired water depth is applied to the field. The uniformity of water distribution depends on an irrigated field and efficiency of on-farm water application. Conclusions point out on the laterals must install parallel to field slope contours for controlling runoff, erosion and on-farm water application. © 2008 Asian Network for Scientific Information.
