Pavlovs'ka T. Horyn' river system: structure, functioning, management.

Dissertation deals with investigations of environmental-geomorphologic problems of the Horyn' river basin. The scheme of investigations of the river system and algorithm of the river system structure analysis has been elaborated. The different time states the Horyn' river system structure and scales of transformation processes have been assessed. The scheme of zoning of the Horyn' river basin by the intensity of these processes is elaborated. Horizontal and vertical deformations intensity of the river beds is calculated. The changes of investigated fluvial system functioning have been ascertained. The impact of the factors spectrum upon geoecological state of the river system is evaluated. The complex of nature protection measures has been substantiated.
