Hydraulic Model Prediction of the Total Load of Sediment Transport in The Euphrates River at The Upstream Ramadi Barrage

Abstract

Examining river engineering properties and bed erosion is one of the most challenging but crucial issues in river engineering and sediment hydraulics, so preventing erosion and sedimentation is one of the primary goals of river management and prediction of river behavior. This research aims to give hydraulic engineers and decision-makers an accurate and dependable sediment transport equation that could be utilized to govern river engineering and modify river morphology. This study evaluated the carried sediments and their estimated quantity upstream of the Ramadi Barrage on the Euphrates River in the Anbar area of western Iraq. Six formulas, including Yang, Shen, Hung, Ackers and White, Engelund and Hansen, and Bagnold's and Toffaleti's, were used to evaluate the applicability of sediment transport in the study area. The performance of these models was assessed based on the precision of the actual sediment load relative to a specified deviation ratio. The analyses indicated that the Engelund-Hansen formula is the most applicable for this section of the river; that concludes, field data indicated an annual total sediment flow of roughly 1, 536, 337 tons.
