Abstract

To design a FURROW IRRIGATION system, various methods have been presented. These methods are based on mathematical or emperical relationships. In this study, three methods of designing FURROW IRRIGATION including: the Food and Agricultural Organization (FAO) method, the Soil Conseravation Service (SCS) method, and the Walker and Skogerboe (W & S) method were evaluted in order to determine the most suitable method for recommendation to executive organizations. To compare these methods in Fars Area an irrigated farm with respect to land slope, topography, soil depth, and so on were selected. After plowing, land leveling, and preparing the furrows, gated pipes were installed at the upper end of each irrigation set. Then, field experiments were carried out to determine the maximum non-erosive inflow rate, constants of Kostiakov infiltration equation, Kostiakov-Lewis infiltration equation, intake family, and advance equation within selected sets of furrows. Afterwards, inflow time and the amount of run off were computed for each treatment. This procedure was repeated for two consecutive years. And the results were compared with each other. The differences in average design infiltration depths and the applied ones calculated by F.A.O., W & S, and S.C.S. varied from (-2 to 3.9), (-7.6 to8.6), and (-19.5 to -35.7), respectively. The results of the analyses indicated that F.A.O. and W & S methods showed closer agreements with field data. Hence, the results of this study can be used in design of FURROW IRRIGATION system at an acceptable level of confidence.
