ОСОБЕННОСТИ СОВРЕМЕННЫХ ИЗМЕНЕНИЙ МОРФОЛОГИИ И ВОДНОГО РЕЖИМА ВОДОТОКОВ В ДЕЛЬТАХ СУЛАКА И ТЕРЕКА

Abstract

On the basis of available hydrological data and results of expedition sounding works the detailed analysis of long-term changes of water levels in the main channels of Terek and Sulak river deltas, vertical and planned deformations of channels, parameters of channels and a river stream is made. The contribution to change of water levels in channels of the water discharges, channel processes, mouth lengthening and sea level fluctuations is quantitatively estimated. Differentiation of delta channels on character and factors of channel processes and changes of water levels is executed. Reliable tools (in the form of empirical dependences) for calculation of water levels on hydrological posts in the Terek and Sulak river deltas on the main factors are created. Received for results allow to optimize water economic actions in deltas of Terek and Sulak, to deepen our knowledge of mouth processes, especially at considerable change of factors of these processes.
