Design Nomographs for Trickle Irrigation Systems
Journal of Irrigation and Drainage Engineering, 1984Nomographs relating discharge rate, plant uptake and soil water potential at a reference point are developed for trickle irrigation systems. The hydraulic conductivity K is assumed to be related to pressure head h by K\do EXP (αh) in which K\do and α are empirical constants representative of the specific soil.

Trickle Irrigation: Prevention of Clogging
Transactions of the ASAE, 1979ABSTRACT TRICKLE irrigation experiments using Colorado River irrigation water on citrus trees in south-western Arizona were conducted to evaluate clogging of emitters and to investigate methods for controlling clogging. Clogging is related to the water quality in terms of the suspended sediment load, chemical compo-sition, and biological activity ...

Trickle Irrigation Uniformity and Efficiency
Journal of the Irrigation and Drainage Division, 1978Expressions are developed and presented for the pressure head available at any point within a trickle irrigation subunit. Histograms are drawn showing the distributions of pressure within typical subunits. Distributions of emitter flow rates within typical subunits are derived from considerations of the effects of pressure differentials and ...
