| ABSTRACT This study shows the possibility to determin the Shatt Al-Arab suspended load through applying mathematical formulas and field measurements of suspended load. According to a hydrological characteristic of the river course, field measurements were accomplished by two main segments, the Northern and the Southern part of Shatt Al-Arab River. The results show that the flow regime of Shatt Al-Arab is a tranquil and turbulent flow due to increasing of inertial forces in relation to viscous and gravitational forces, as a result of increasing flow depth and velocity in addition to decreasing of median grain size of bed sediments. The observed total suspended load in the Northern part was ranging between 20.01-26.91 Kg/Sec at Abu Al-Kasseb and Al-Khorah sections, respectively. While its range in the Southern part between 120-144 Kg/Sec at Al-Fao and Karun confluence, respectively. The present study recommends the use of Yang’s (1980) equation to calculate the stream power according to Bagnold (1980) formula because it gives much closer results to the measured data, in contrary to that calculated by Bagnold (1960) formula. | ||
