Abstract
The main regularities of the motion of water and sediment at the mouths of different types are described. Examples of river mouths of those types are given. The principles of modern classification of river mouths, which takes into account the hydrological processes in mouth zones, are used for zoning the mouth area of the Yenisei R. The main regularities in the interaction of sea and river waters and sediment transport, typical of estuarine-deltaic mouth type, are considered. The parameters that determine the type of water circulation and stratification in an estuary are evaluated. The main attention is paid to studying the mixing of river and sea water at the estuarine-deltaic mouth of the Yenisei and the mechanism of sediment motion at the mouth in the presence of delta under the joint effect of river runoff and tides.
