Resumo
This work aimed to compare different methodologies for designing paired laterals of drip irrigation systems on uniformly sloping fields. For this purpose, the methodologies proposed by Keller e Bliesner (1990), Jiang e Kang (2010), and Monserrat; Barragan e Cots (2018) were evaluated. The length of uphill and downhill lateral lines, distribution uniformity (DU), flow, and pressure variations were calculated for both topographic conditions. The Keller e Bliesner (1990) methodology generated the best design for paired laterals, with the lowest DU difference between the uphill and downhill sections; also, the flow variation remained under the 10% limit. The second-best performance was obtained by the method of Monserrat; Barragan e Cots (2018). Jiang e Kang (2010)’s procedure was the least adequate, generating a 10.9% flow variation in the uphill section.
