Estimation of the current state of distribution of the drain of water and deposits in main sleeves of Don river delta
The method for the evaluation of water flow in non-stationary water streams at considerable oscillations of current velocity in waterways caused by long waves of sea origin is developed. Estimates of sediment transport at separate cross-sections of water streams are received. As a result of investigations described new data on hydrological regime of the Don river delta has been obtained. Kinematics of the delta streams is revealed and present distribution of water flow and that of sediment transport in the main waterways of delta are estimated. The method enables to define distribution of water flow and sediments in waterways of Don river delta with minimum expenditures using only one small size vessel and standard hydrological equipment.
