Irrigating with cut-back furrow streams

Sakkas, J.G. / Hart, W.E.

Nonuniformity of water distribution in irrigated fields results from unequal intake-opportunity times along run; cut-back of inflow (as suggested by previous workers) allows large initial stream and was proposed to eliminate this inequality; this requires variable number of furrows to be brought under irrigation at beginning of successive time intervals; mathematical analysis of variation is presented and results are summarized in tables which give number of furrows started at beginning of each time interval and being irrigated during each time interval; these tables enable irrigator to correctly distribute available quantity of water and, when using siphons, to estimate number of siphons required.
