Abstract (English):
In the Mezen bay and estuaries Mezen and Kuloy can be high concentrations of mud suspension there, involving the formation at times mobile suspensions and settled mud. Within estuaries the river water is mixed with the sea water by the action of tidal motions, by waves on the sea surface and by the river discharge forcing its way to the sea. Nearly all shallow tidal estuaries, where currents exceed about 1,0m s-1 and where sand is present, have sand waves. Sand waves have a variety of cross-sectional and plan forms.

SEDIMENT DYNAMICS
Эрозионно-аккумулятивные процессы в Мезенском заливе обусловлены приливо-отливными течениями, ветровым волнением, формированием вдольберегового потока наносов. Трансформация вдоль берегового потока происходит вследствие абразии берегов, взмучивания донных отложений, аккумуляции наносов в зонах замедления скоростей течений. Важной причиной изменения вдольберегового переноса наносов является поступление взвешенных наносов из устьев рек Мезени и Кулоя.
