Abstract: 

The area of the Ghareh-Aghaj river watershed basin, from the source area to the Kavar dam-site at down-stream, is estimated to be about 1600 km2. The river flows in a southeasterly direction, passing by 20 km southwest of Shiraz. In this research, the total sediment yield of the Ghareh-Aghaj river to the dam-site was calculated by using hydraulic and sediment logical methods. These methods indicate flow depth, channel slope, river width, flow velocity, angle of repose and particle size characteristics (d10, d30, d60 and d90). Furthermore, the water temperature and the kinematic viscosity of the water, due to its effects on the movement of sediments, were determined. The suspension load rate of the river was estimated at 765040 ton/year by using the Yang Method. This research shows that the bed-load rate of the river is about 21% of the suspension load according to the Meyer-Peter & Muller Method.
