Abstract (English):
The numerical method on the assessment of deformation volumes of bed load with account of natural processes in estuarine navigation channel is developed on the basis of time-spatial database and geoinformation methods for natural and construction systems monitoring. The method is applied to fulfill the analysis of navigational channels stability due to natural sedimentation and fairway depth maintenances. The method is enhanced due to necessity of the assessment the dredging volumes calculation during dredging works by means of the balance equations for navigational sections deformation under natural and anthropogenic impact.

Речной поток, который выходит из устья рук. Быстрого, претерпевает большие изменения на баровой части, где расположено МПК и струенаправляющая защитная дамба. Поток сначала растекается над речным склоном бара, который имеет прорезь в виде МПК. После этого поток снова суживается, обтекает оголовок Птичьей косы и растекается на правому забровочному пространству.
