Abstract

The article provides discussion about sediment transportation and its velocity, also main attention given to analyse of hydrometeorological parameters and sediment regime of The Surkhandarya River which main source of South Surkhan water reservoir. In this research we used materials from exploitation and field studies for the water reservoir of South Surkhan. Final estimations demonstrate that at the Shurchi hydrological station of the Surkhandarya River, the average sediment concentration is 2.02 g/l or 2 kg/m3. River sediments were determined in volume ratios and in masses. Module of erosion is 509 tons/km year the layer of erosion 0,443 mm/year erosion meter is equals to 2257 years.
