Cheroi A. Water and sediment flow moreover morphological processes in Danube estuary area.

Object of research is the Danube estuary area. The work purpose is the estimation of water and sediment flow characteristics, and studying of branch and coastal zone dynamics of the Danube delta. The experimental, hydrometric, statistical, analytical and balance methods have been used. The description of modern hydrographic network, water and sediment dynamics in the Danube delta and its runoff distribution on delta branches, morphological processes, which take place in delta branches and coastal zone are considered. For the first time the author: The method for calculation time channel lag on the Ukrainian site of the Danube; modern seasonal redistribution of flow on delta branched is investigated; short-term redistribution of flow on Bistriy branch is investigated; methods of measurement and calculation of a river sediment flow are improved. Recommendations of dissertational work are introduced in practice of Danube GМО work. The modern and reliable hydrological information, as base for scientificsubstantiations of different water-supply projects and measures, is received.
