Surface Irrigation is a kind of irrigation where gravity works its best. 0000207022 00000 n 5.1 Objective and scope of design 5.2 The basic design process. Surface irrigation design requires the estimation of parameters that define the infiltration of water into the soil and the resistance to water movement caused by the soil surface and vegetation. Surface irrigation is where water is applied and distributed over the soil surface by gravity. In flood irrigation, the water is per- mitted to cover the surface of the land in a continuous sheet. 130 0 obj << /Linearized 1 /O 133 /H [ 1721 742 ] /L 680252 /E 313204 /N 19 /T 677533 >> endobj xref 130 56 0000000016 00000 n 0000096984 00000 n j�{�Q��FE�J� Common surface irrigation systems used are rill irrigation, furrow or border irrigation.
