Abstract
The spatial and temporal peculiarities of sedimentation in the channel of the Mudyug towers in the seaport Arkhangelsk are considered according to the data of the bottom relief survey. Patterns of spatial distribution of sediment in the channel during winter navigation and storm and monthly periods of summer navigation are constructed using difference in depths. The intensity of sediment thickness is assessed. It has been revealed that the sedimentation has a seasonal nature, the largest volumes of sediment are formed near a shallow bar. In the south and central part, a strong record is observed, in the north is insignificant and weak, on the whole in the channel the sedimentation can be characterized as medium.
