Abstract

The paper presents new data on the morpholithodynamic regime of the foredelta and deltaic branches of the Northern Dvina River. Based on data from field sonar investigations, the bottom structure and lithology of bottom sediments are described. Using hydrographic and topographic charts and satellite images, we traced the dynamics of deltaic branches and bottoms in the outfall offshore zone of the Northern Dvina River for the period of 1832–2013.
