A model based on a stepwise technique is developed considering the head losses and flow regime changes through the system. The model was run for 12 possible scenarios, under two terrains of 0 and +0.25% slopes (upward), with three (2, 3 and 4 mm) and two (12 and 16 mm) microtube ...
This comprehensive book contains chapters on the principles of drip irrigation, water in the soil, irrigation requirements (and methods of determining them), water movement and distribution in drip-irrigated soils, physiological aspects of drip irrigation, fertilizing with drip irrigation, principles for...
The hydraulics of IDEal drip irrigation system components were analyzed under controlled laboratory conditions and the results can be applied to the design of IDEal systems. The hydraulic loss coefficient for the lateral-submain connecto... Thompson, Evan J. - Utah State University. 被引量: 0发...

Because of the low operating pressure and low friction loss due to low flow rate in a drip irrigation system, the pressure variation of a lateral line is easily affected with slopes and results in the increase or decrease of the emitter flow uniformity. Therefore, the elevation difference along...
The paper presents a general shape of energy gradient line which can be applied to estimate distribution and variation of emitter discharge along the lateral. A design chart is presented for determining an acceptable combination of lateral length and inlet pressure of a drip irrigation system.关键...
Drip irrigation, fertigation and micro-irrigation are methods of watering crops that delivers water directly to the roots of plants through a network of tubes, pipes, and emitters. This precise delivery system conserves water by minimizing evaporation and runoff. It promotes healthier plants by ...
