This study evaluated a drip-gravity irrigation system implemented in Barajin Park at the north of Qazvin province. In order to carefully examine the existing conditions of the field visit, the effective parameters in the evaluation were measured for all laterals in the selected section, including 13 laterals. The results showed that the water uniformity distribution was unacceptable due to the significant elevation difference. Note that no filtration system was used; hence, it was impossible to use a pressure regulating emitter (PC) because these emitters are sensitive to chemical and physical clogging. To improve the water distribution conditions, applications of 1) using flow control valves, 2) changing the diameter of the pipes, and 3) using two types of conventional drippers (Non-PC) with different scenarios and modeling in EPANET software were investigated.
