study of suspended sediment transport at tigirs river- upstream kut barrage (iraq)

estimation of suspended load for tigris river upstream of kut barrage is very important issue because of the large amount of sediments that accumulate upstream the barrage. the study includes field and laboratory work, five cross sections allocated with study reach for the purpose of field sampling and measurement of hydrodynamic parameters. the result show that all bed samples are silt clay and suspend about bagnold on shield diagram. the comparison between predicted suspended sediment discharge by bagnold formula and field observation of suspended sediment discharge show good agreement with equal r² of 1.0 and rmse range from 0.9 to 2.4.
