Аннотация:The paper contains unique information on the factors and regularities of the dynamics of marine edge and hydrographic network of the Volga, Ural, Terek, Sulak, Kura and Sefidrud river deltas. Large-scale fluctuations in the Caspian Sea level, river runoff, wind-wave conditions and morphological structure of nearshore zone in the river mouths, local water management activities are included in the list of the main factors. Current estimates of their magnitude and long-term variations are also given. The differences are shown, the regularities and the factors of the dynamics of the delta coastline in periods of large-scale fall (until 1977) and increasing (in 1978-1995) Caspian Sea level are established. Quantitative evaluations and cartographic schemes of this process are obtained. A separate paper section contains the results of a detailed analysis of dynamics of the hydrographic network and channel processes in the Caspian deltas. Regularities of this type of morphological processes are considered on the example of the Volga and Terek deltas. Morphological processes in deltas are studied from the standpoint of their negative impact on local environmental conditions and economic activity
