| Freshwater scarcity has become a global issue, and agriculture is the major water consumer, pushing researchers to look for methods to improve water usage efficiency. The research aims to create design software for a simple low-head bubbler as a water-saving alternative to a traditional furrow irrigation system. The specified bubblers, having an inside diameter (ID) of 8.8 to 13.6 mm and a height of 0.5 m, were hydraulically evaluated in the lab at low effective pressures ranging from 1 to 13 kPa. There are two methods for estimating bubbler discharges (qb) by the design model: using equation from the laboratory bubblers evaluation (E1) or using theoretical calculations (E2). The model calculates discharge uniformity (CU) until it is ≥ 85 %, at which point it stops and displays determining the lateral flow rate (QT), pressure (HT), and length (LL) for each value of CU ≥ 85 - 90, ≥ 90 - 95, and≥ 95 %. The correlation factor (R2) between measured and estimated qb by (E1) and (E2) was 0.98 and 0.93 % for ID 8.8 mm and (0.76 and 0.81 %) for ID 13.6 mm, respectively. Although the R2 between measured and predicted qb was reduced by ID increasing, the correlation remained high. As a result, an ID of 13.6 mm or less is often recommended. According to the results, using this model to design a simple low-head bubbler irrigation system is both effective and reliable. In terms of water conservation, it could be a viable alternative to traditional furrow irrigation. conservation, it could be a viable alternative to traditional furrow irrigation. | ||||
