Titre de série : Journal of irrigation and drainage engineering, 2 Titre : 2 - D Infiltration equations for furrow irrigation Type de document : texte imprimé Auteurs : Fok, Yu-si ; Axe, M. ; Chiang, Shan-Hsin Mention d'édition : ASCE Editeur : ASCE Année de publication : 1984 ISBN/ISSN/EAN : CI-06264 Note générale : Two - dimensional (2-D) infiltration equations for furrow irrigation expressed in explicit algebraic forms are developed and based on four consecutive time intervals which were derived in a previous study (1). From another study an extension is made for 2-D infiltration (4). Since the geometric cross section of a furrow can have different forms, a simple rectangular cross section is used for illustration. Two - dimensional infiltration in a furrow is assumed to be a composite of 1-D and 2-D infiltration components. These components of infiltration are computed using developped 1-D and 2-D infiltration equations obtained from previous studies.

Titre de série : Journal of irrigation and drainage engineering, 2 Titre : Dimensionless runoff cuves for irrigation borders Type de document : texte imprimé Auteurs : Yitayew, M. ; Fangmeir, D. D. ; Axe, M. Mention d'édition : ASCE Editeur : ASCE Année de publication : 1984 ISBN/ISSN/EAN : CI-06263 Note générale : Nondimensional runoff cuves useful in the design of reuse systems are presented for free outflow irrigation borders. Pertinent open channel variables affecting runoff in border irrigation, including inflow rate, surface resistance, border slope, soil infiltration characteristics, application time, and length of border, were studied and their effects presented. Maximum advance distance/ which is of interest in designing border irrigation systems, is also given by the zero runoff cuves. A zero -inertia mathematical model was used to develop the nondimensional predictive graphical solution in terms of four reduced variables.

Titre de série : Journal of irrigation and drainage engineering, 3 Titre : Optimal channel cross section with freeboard Type de document : texte imprimé Auteurs : Guo, C.-Y. ; Axe, A. M. ; Hughes, W. C. Année de publication : sept-84 ISBN/ISSN/EAN : CI-06261 Note générale : Methods from calculs may be used to determine a channel cross section which minimizes hydraulic resistance or alternatively, determines the least cost channel dimensions. In either case, established procedures ignore channel freeboad. The traditionnal methods of channel geometry optimization are reformulated to include freeboard considerations. The results are shown to revent to traditional solution when the freeboard parameter is set to zero. A graphical solution is provided to simply the resulting equation.

Titre de série : Journal of irrigation and drainage engineering, 4 Titre : Irrigation water delivery for equity between users Type de document : texte imprimé Auteurs : Bishop, A. A. ; Axed, M. ; Long, A. K. Mention d'édition : ASCE Editeur : ASCE Année de publication : 1983 ISBN/ISSN/EAN : CI-06265 Note générale : The problems of getting irrigation water to lands to be irrigated in the right amount, at the right place and at the right time are discussed. A brief review of the methods of irrigation water delivery is presented alone with a more detailed discussion of rotation delivery. A step by step detailed procedure is shown for setting up a rotation delivery shedule. The resulting schedule provides for equity between users with respect to volume of water per unit area and time of irrigation turn (daytime or night).
