Abstract

Since TRICKLE IRRIGATION system efficiency depends on the physical and hydraulic characteristics of the drippers and specially water application uniformity, therefore evaluation of drippers as the most important section of a TRICKLE IRRIGATION system will be very important to have an efficient irrigation system. The objective of present study was to measure discharge rates of three different kinds of emitters (including Siplast, Inline168 and Katif8) at four different pressure levels of 50, 100, 150 and 200 kPa to assess the HYDRAULIC PERFORMANCES, calculating the coefficient of manufacturing variation, water DISTRIBUTION UNIFORMITY of emitters and emitter discharge exponent, in order to establish the emitter’s flow rate sensitivity to pressure and comparing the results to the manufactures’ specifications. Based on results, Katif8 was classified as pressure compensating and inline168 and Siplast were classified as non-compensating pressure as expected. All three emitters distributed water uniformly at all operating pressures. Results indicated that designing TRICKLE IRRIGATION specially relationship between discharge and pressure should be based on reliable test data, not on manufacturer´s supplied data.
