Abstract

Deltas are formed as a result of river-sea interaction. They respond to natural and anthropogenic changes in regime of these water objects. Type, structure, hydrological regime and landscape of nontidal deltas are often subject to irreversible changes following the changes in river water and sediment runoff, sea level, and wave action. In consequence of this, delta dynamics can be considered as an efficient indicator of large-scale changes in global and regional regimes of rivers and seas. The paper is aimed at studying the dynamics of deltas of rivers flowing into the Black and Mediterranean seas under the impact of changes in river water and sediment runoff and sea level.
