Surface Irrigation Design José M. Gonçalves, André P. Muga and Luis Santos Pereira CEER Biosystems Engineering Research Center, Institute of Agronomy, Tech nical University of Lisbon Portugal 1. In Surface Irrigation, water is applied and distributed over the soil surface by the help of gravity. irrigation analysis and were successfully applied to simulate steady and unsteady flow with solute transport in furrow irrigation (Burguete et al., 2009a). Surface irrigation are characterized by their operation simplicity; however, design and management are complicated (Burguete et al., 2009b). Holzapfel, M.A. 0000010970 00000 n 0000026863 00000 n If a field is level in all directions, is encompassed by a dyke to prevent runoff, and provides an undirected flow of water onto the field, it is herein called a basin. 0000065014 00000 n Download as PDF. This process can be divided into a preliminary design stage and a detailed design stage. Surface irrigation is often referred to as flood irrigation, implying that the water distribution is uncontrolled and therefore, inherently inefficient. 0000002790 00000 n Surface Irrigation at Alice's Garden - Duration: 1:19. Due to their near-zero surface slope and closed boundaries, basin irrigation is appropriate for crops that can tolerate inundation. 0000021785 00000 n 0000064587 00000 n In general, it is more labour intensive than other irrigation methods.
