Abstract: A new formula have been suggested for estimating of suspended sediment load for a reach of Tigris River. This reach is located in upstream of Al-Amarah barrage, Maysan Province, South of Iraq. The total number of the observations was fifty-six these observation have been obtained from pervious study. Pi theorem and general regression among effective parameters are used for developing empirical formula. The effective parameters represent the characteristics of both flow and sediment. These parameters include density of water (ρ) solid particles (ρs), viscosity of water (ν), mean diameter of particles (d50), acceleration due to gravity (g), river flow velocity (V), river width (B), particles settling (fall) velocity (w-s) and maximum flow depth (h). Based on the magnitude of determination coefficient (R2) a good agreement between the loads calculated by the suggested formula and the observed data have been achieved.
