DESIGN OF SURFACE IRRIGATION, LECTURE SUPPORTING MATERIALS 6 Fig. The design, managing, and operation of irrigation systems are crucial factors to achieve an efficient use of the water resources and the success in the production of crops and orchards. 0000019972 00000 n In flood irrigation, the water is per- mitted to cover the surface of the land in a continuous sheet. Common surface irrigation systems used are rill irrigation, furrow or border irrigation. We stock over 10,000 irrigation and landscape products, including lawn sprinklers, Surface irrigation is the introduction and distribution of water in a field by the gravity flow of water over the soil surface. Surface irrigation, with which this chapter deals, includes the general methods of flood and furrow and cor- rugation irrigation. Eng. 0000066453 00000 n 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. 0000003070 00000 n Micro Irrigation for Small Scale Farming – An overview about technologies and methods 1. 0000002867 00000 n 0000180089 00000 n 0000064359 00000 n 0000001462 00000 n irrigation areas as for surface irrigation, however subsurface irrigation may allow for higher nutrient uptake in the same location.
