1 Palmer, J. D.; Clemmens, A. J.; Dedrick, A. R.. 1989. Several sources of nonuniformity in irrigation delivery flows. Journal of Irrigation and Drainage Engineering, 115(6):920-937.
(Location: IWMI-HQ Call no: PER Record No: H05826)
A lateral canal in a southwestern U. S. irrigation district was instrumented for continuous monitoring. Deliveries were flexibly scheduled; farmers arranged timing, rate and duration with the district. The distribution of measured variables showed that the lateral was operated under a wide variety of demand and operational conditions and that farm delivery flows were frequently not uniform due to changing conditions along the lateral. Flows that are unpredictably variable affect the performance and evaluation of on-farm application systems and, unless controlled, can negate the benefit of flexible scheduling (more precise management). Statistical analysis of 286 deliveries to nine farm turnouts identified a number of sources on nonuniform flows which were a combination of canal hydraulics and operational characteristics. Time of year that deliveries occurred was shown to affect uniformity, as were median flow rate, delivery duration, and location of turnouts, both within a pool between two check structures and along the lateral. Identifying source of nonuniformities is an important first step in devising structure and operational control to improve delivery uniformity.

The management of surface-drained level basins, where a portion of the initially applied water is drained out from the inlet end of the irrigated basin, is reviewed. Design procedures regarding basin and channel layout, and land leveling are presented. Drainage is made possible by properly configuring of an earthen water supply channel relative to the basin surface. The proportion of drainable water from furrows (ratio of the volume drained from a furrow to the volume stored in the furrow at time of irrigation cutoff) ranged from 25% to 45% depending on the furrow length. Such drainage quantities would result in increased potential application efficiency. The utilization of the surface-drained level basin systems for rice production in rotation with other field crops is discussed.
