Ecological Systems and Devices Annotation << Back Geomorphological structure flood-plain of Volga-Achtuba and Volga deltas in a zone of Astrakhan sulfur and gas-condensate deposit influence. Gol’chikova N.N., Kudinov V.V. The analysis of genetic types and subtypes of a relief show, that in formation of a modern relief a determining meaning have events in verchnechvalinic and the modern stage have played. In limits alluvial-flood and alluvial-deltoid plains the leading mean in formation of a relief belongs fluvial to processes: erosion and accumulations. Because of intensive intervention of activity of the human in the lithosphere, a natural course relief forming it is broken. The geomorphologic background in flood plain and delta in connection with regulation of a flow of the Volga waters, levelling of a relief during a plowed land has essentially changed for last 40 years.
