Obodovskiy O. Hydrology-ecological region analyze of channel process- Manuscript.

Theoretic basis of hydro-ecological estimate of fluvial process are substantiated and formulated in this work. Working out a structure to hydro-ecological analyses of channel process. Our researchers to estimating channel process for manifestation and introduce criterion of dependence to the value bed of the channel horizontal and vertical deformation and sediments that formed riverbeds. Substation and realization erosion proof stable of riverbeds for Ukrainian rivers. Developing and making use of new position in reference ecological admissible expenditure of water (EAE) and ecological flow necessary (EFN) as main criterion value hydrological flow of the riverbeds. Proposed the main methods aspects for studies fluvial process in the lower pool of HPS and used for Dnipro's stations. The main positions hydro-ecological estimate of fluvial process are developed and realized for Carpathian rivers. Formulate the main positions of recommendation and measure as improve a condition to river channel regime of Ukraine.
