Investigation of so called New Terek delta forming and development has been characterized. This delta has appeared at Eastern coast of the Agrachan Peninsula after direction of Terek waters into Western Caspian by artificial cannel. New delta has been forming under fast sea level rise conditions at 1978–1995, some its afterwards downing and stabilization. A series of 6 maps of delta status at various stages of its forming was compiled, so as a series of 4 dynamics maps of some delta elements. These maps show main influence of sediments discharge to delta growth even at sea level rise conditions. The results may be used in modeling of coastal zone response to expect World ocean level rise.
