Sediment transport in rivers is an important and complex process. It is very important to know the nature and quantities of sediments transported in course of rivers to achieve prudent water management. Due to the presence of most of the important projects on or near the banks of the river in the study area, so there is always a fear that these projects will be affected by the processes of erosion, transport, and sedimentation among the decision makers. Therefore, there is a need to develop our knowledge of the suitable equations that can be applied with acceptable accuracy to obtain satisfactory results for monitoring the processes of erosion, sedimentation, and transport that occur in River path to monitor and anticipate the changes taking place in the areas of the riverbanks. This study was carried out to check the reliability of different sediment transport formulas using data collected from the Euphrates River at the thermal power station in Al Anbar province, Iraq. The study also aimed to select the best formula for this site. Hydrological data have been collected. These were used for computing the total sediment load in the river at a specified cross-section using common sediment transport formulas ascribed to Ackers-White, Bagnold, Yang, Colby, Shen and Hung, and Engelund-Hansen. The performance of these formulas was assessed based on the accuracy of the predictions of the observed sediment load within a limited discrepancy ratio. The evaluations showed that the Engelund-Hansen formula represented the best formula for this river reach.

河流中的泥沙输送是一个重要而复杂的过程。了解谨慎的河流运输过程中沉积物的性质和数量对于实现审慎的水管理非常重要。由于研究区域中河岸上或附近的大多数重要项目的存在，因此始终担心这些项目会受到决策者之间的侵蚀，运输和沉积过程的影响。因此，有必要发展我们的知识，使这些方程能够以可接受的精度被应用，以获得令人满意的结果，以监测河道中发生的侵蚀，沉积和运输过程，以监测和预测河道中发生的变化。河岸地区。这项研究是使用从伊拉克Al Anbar省火力发电厂的幼发拉底河收集的数据来检查不同沉积物输运公式的可靠性的。该研究还旨在为该站点选择最佳配方。已经收集了水文数据。使用Ackers-White，Bagnold，Yang，Colby，Shen和Hung和Engelund-Hansen的常见输沙公式，将这些用于计算特定横截面的河流中的总输沙量。这些公式的性能是基于有限的差异率内观察到的泥沙负荷预测的准确性进行评估的。评价表明，Engelund-Hansen公式代表了该河段的最佳公式。
