Design and evaluation of center pivot irrigation system (DEPIVOT) is a method for assessing the technical efficiency of center pivot sprinkler irrigation systems, such as operating speeds, for various requirements. Catch cans method was conducted to evaluate the distribution uniformity (DUlq) and Christiansen coefficient of uniformity (CU), catch cans method was used to evaluate two center pivot irrigation systems: CP1 (center pivot, 6'' diameter number of the nozzle orifice 17 attached with 10 L min⁻ˡ flow) and CP2 (center pivot, 8" diameter number of the nozzle orifice 25 a􀆩ached with 20 L min⁻ˡ flow) under three speeds (50 %, 75 %, and 100 % of the system's normal speed, or 15 m h-1, 22.5 m h-1, and 30 m h-1, respectively). All 18 can tests were entered into the DEPIVOT simulation model, which simulated the DUlq and CU for each test separately, allowing the DEPIVOT simulation model to be validated by statistically comparing the simulated and measured data in the field. The validation process using the DEPIOVT simulation model was found accurate, with a success rate over 95 %, making it a recommended method for validating the efficiency of center pivot irrigation systems.
