Three sediment sizes (0–150, 0–200 and 0–250 μm) and two flow rates (36 and 72 m3·h−1) were tested. Numerical simulations were conducted to examine the mechanisms behind sediment removal. Compared with the control, the use of inclined tubes significantly reduced the sediment concentration by 34%–64% and the median particle size by 36%–65%. V-shaped tubes outperformed straight tubes, especially the ITV2. This improvement was attributed to flow redistribution, expanding the sedimentation area, while the sedimentation tubes promote better flow uniformity than straight tubes through secondary flow redistribution. Furthermore, the inclined tubes showed notable differences in the removal of large, medium and small particles, with the most significant reduction in medium-sized particles, achieving a 36%–65% decrease compared with that of the control. This study clarifies the effects of different inclined tube designs on fine sediment removal, providing insights for optimizing sedimentation tanks in agricultural irrigation systems.\u0000 </div>","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"75 1","pages":"159-172"},"PeriodicalIF":1.7,"publicationDate":"2025-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146154808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model's accuracy was tested via nine ET₀ equations, including Penman–Monteith (PM), Penman–FAO (PFAO), Hargreaves–Samani (HS), Blaney–Criddle (BC), Turc, Evaporation Pan (PAN), Jensen–Haise (JH), Priestley–Taylor (PT) and FAO–radiation (RAD). The results revealed that AquaCrop effectively simulated evapotranspiration, dry matter and yield during calibration and validation. Importantly, the model demonstrated acceptable accuracy in simulating wheat yield across all evaluated ETo calculation equations. The normalized root mean squared error (NRMSE) values were 0.08 for HS, 0.09 for Turc, 0.10 for both BC and PM, 0.11 for PT, 0.14 for both PAN and PFAO and 0.17 for JH. This study highlights the potential of using simplified ETo equations such as HS, Turc, BC, PAN and JH instead of more complex equations such as PM, PFAO and PT as a practical approach for modelling crop growth and yield in regions with limited meteorological data.
