Abstract

The long-term changes of a sediment discharge, acting in a river mouths of the southern Russian seas are investigated. The influence on them of climatic fluctuations of a water drain, anthropogenesis losses of a drain, creating of large reservoirs regulating a drain is appreciated. It is established that alongside with changes of a water discharge the nonsteady current condition of system "water – bed - sediments" (both on upper sites of the river, and in the river mouth) renders an appreciable influence on a sediment discharge in river mouths.

Keywords: sediment discharge, restored natural water discharge, observed discharge, river mouths, the abounding in water period, period with little water, the influence of reservoirs
