ANALYSIS OF MEASURES TO COMBAT THE VOLGA-CASPIAN CANAL SEDIMENTATION

Purpose: to assess measures reduce the canal sedimentation and, accordingly, volume of repair dredging by constructing protective structures, which are proposed be used within boundaries permitted shallow-water dumps protect from bottom soil backbone space and regulate water flow into channel. Materials methods. The Volga-Caspian Sea Navigation Canal (VCSNC) plays role a connecting link single deep-water highway Caspian Azov-Black Sea, Baltic Northern basins through ports Olya Astrakhan. in continues throughout year; winter, ships piloted with support icebreakers. ship's passage river part passes along Bakhtemir branch – natural continuation bed Volga delta Volga. One main factors complicating conditions for normal operation VCSNC is its sedimentation, caused solid runoff Volga, surge, wind wave ice phenomena. A different combination these components entails deformations sediment deposition, vary year year, both channel individual sections. possible measure construction shallow being carried backwater Results. Four options constructive solutions structures using geotubes geobags various combinations, preparing central dam were considered. Conclusions: it use composite traditional materials.
