Quantitative Evaluation to the Sediment Load at a Part of Euphrate River in Center of Iraq

Estimates sediment transport in Iraqi Rivers are essential for effective rivers management, particularly when de - livery rates is potential threat to environment and ecological systems. Therefore, this research was performed for estimating sediment transport rates in a certain reach from Euphrates River downstream Al Hindiyah Barrage and examine the stat of Entrainment Rate Esi of bed sediments under a unsteady stream flow. In spite of complexity and the difficulty of conducting measurements, the sediment load were measured with satisfactory perfection to achieve acceptable results for monitoring this river reach. The acoustic Doppler current profiler (ADCP) technique were used to measure velocity distribution, cross section profiles
