Drift flowing of the river Tom (the Western Siberia)

Abstract

The results of studying the flow of tractional and suspended sediments of the river Tom near the city Tomsk have been presented. It is shown that it is preferable to apply G.I. Shamov's method to determine the losses of tractional particles. It is stated that average total solid drift near Tomsk (undercurrent of the Tom) amounted 47,89 kg/day or 1510179 t/year within 1986-2005. Its bulk includes suspended particles (65,4 %). Average flow of tractional drifts amounted 16,57 kg/day or 522519 t/year. The recommendations on bed-correcting are given.
