Flow diversion from the outerbank of channel lead to formation of a transverse flow component having an opposite alignment withthe secondary current in bed and consequently transferring a part of the sediment bed load to intake.The diversion of flow will change the flow pattern in the river bend and decrease the energy of thesecondary current in this location. In this paper the effect of flow diversion to sediment entering theintake in a 52 degree diversion angle was investigated. The results have shown that the low ratios ofdiverted flow has a little effect on the secondary current, and also this current causes the repelling ofsediments from the outer bend of the river. Along with the increase of the ratio of diverted flow, theenergy of secondary currents decrease and the ratio of sediment diversion increases. In a specific valueof flow diversion, the secondary flow was fully damped. After that, the sediments entering the intakehave a higher increase compared to the previous situation. The results also showed that the trend ofvariations of diverted sediments with the flow diversion generally follows the S shape.}, keywords = {}, title_fa = {تاثیر انحراف جریان بر رسوب ورودی به آبگیر با زاویه انحراف 52 درجه در رودخانه سینوسی}, abstract_fa = {}, keywords_fa = {}, url = {https://jhyd.iha.ir/article_85503.html}, eprint = {https://jhyd.iha.ir/article_85503_ba57ff23601417998d0996aa3daac9e8.pdf} }
