Farm irrigation system design, Kafr El Sheikh, Egypt

Part I reviews the Soil Conservation Service level furrow and level border design methods which have been used, as well as the effects of design parameter changes on irrigation performance, and presents HP-9825 and HP-67 computer and calculator programs for design. In Part II, design considerations for the Abu Raya area (and for areas with similar conditions) are reviewed by an analysis of the individual factors and parameters which affect level farm irrigation system design. The methods used in this case study should be applied in developing design recommendations in major areas having similar conditions. Part III of the report reviews the experience of the Kafr El Sheikh Team in implementing level irrigation designs in Abu Raya. Comparison of the improved methods with conventional methods shows that consistent water savings, labor savings, time savings, and improved efficiency result. The improvement package also gave improved crop yields. Design analysis is included to show how further design improvements should be made. Level irrigation design programs and user instructions for the HP-9825 and HP-67 are included in appendices. Advance-recession data plots from several farms where designs were constructed and evaluated are given in Appendix C. (Author abstract)
