The Development of Automatic Irrigation Structures and Devices

(missing...) developed during the study are discussed in this paper. Brief mention will also be made to those structures for which development has been discontinued, since this information may be of interest to other researchers and possibly used in designing specialized structures. During the study, emphasis was placed on developing fully automatic structures which would operate from the energy of water flowing in the ditch and not require an external power source. The structures shown in Figure 1 were developed and field tested by the authors while located at Boise, Idaho
