Hydraulic calculation lateral in drip irrigation

Abstract

Drip irrigation systems are widely used worldwide to satisfy the water demand of agricultural crops. It is known that drip irrigation technology has a number of other advantages, such as intensive irrigation, automation, and water economical benefits. The methods which is available in hydraulics are widely used in the calculation of drip irrigation design. One of the most important issues in the drip irrigation system is the correct estimation of the discharge coming out of the drippers. As known from hydraulic calculations, it is necessary to take into account the pressure when determining the discharge coming out of the emitters. It should also be noted that discharge from emitters has a special effect on pressure losses in drip irrigation systems. The article presents the results of the research conducted in natural field conditions on the assessment of hydraulic processes in drip irrigation systems. As an object of research, the cultivated field of the “Sharifjan oglu Akhmadjon” farm in Rishton district, Fergana region was selected. The results of measurement work at 36 points of the research object are highlighted. As a result of the conducted research, recommendations for determining discharge in irrigation pipes were developed.
