Water flows over the soil by gravity for surface irrigation. Three Surface Irrigation MethodsBasin irrigationBorder irrigationFurrow irrigationUncontrolled flooding -^Requirements for Optimal Simple approach to surface irrigation design: Theory (1) A. Clemmens. Surface irrigation (flood irrigation): It is most common form of irrigation where water is applied and distributed over the soil surface by gravity. It comprises traditional systems, developed over millennia, and modern systems with mechanized and often automated water application and adopting precise land-leveling In this module, different surface irrigation methods, namely: (a) flooding or basin, (b) furrow, and (c) border are discussed; while the design principles and application of sprinkler and drip irrigation systems will be covered in the next two modules (see Figure 1). Sprinkler irrigation applies water to soil by sprinkling or spraying water droplets from fixed or moving systems. Download chapter PDF. Key words. Surface irrigation phases. Border. Basin. Figure 1 three main methods of irrigation are surface, sprinkler and drip/micro. Water flows over the soil by gravity for surface irrigation. Published Engineering, Agricultural and Food Sciences. The State of Washington Irriga-tion Guide provides recommendations on surface irrigation system design and operation by soil type The purpose of this chapter is to present methods for the design of modern surface irrigation systems, where modern implies a reasonable control over the water supply. Infiltrometers. Reuse system. Microirrigation WinSRFR. Evaluation. Furrow. Sprinkler irrigation applies water to Methods of Irrigation. Infiltration. The movement of water over the soil When border irrigation or other flooding methods are used, dikes or borders are constructed to contain the flow within the desired field area. are not Surface irrigation is the oldest and most widely used irrigation method, more than% of the world’s irrigated area. The chapter focuses on the three major categories of surface irrigation; design of rice paddies and methods such as contour levee, contour ditch, wild flooding, etc. Surge irrigation 8, · three main methods of irrigation are surface, sprinkler and drip/micro.
