Konovalenko O. Hydromorphodynamic assessment of channel deformations for Mountain Rivers on Upper Tizsa basin example

Thesis for an academic degree of Candidate of Geographic Sciences in the specialty 11.00.07 -Hydrology of land, Water recourses, Hydro-chemistry.- Kyiv National Taras Shevchenko University, Kyiv, 2007. The river's hydrological regime as typical bed-formation factor was discovered. The methodic of hydromorphodynamic assessment was elaborated. The hydromorphodynamic assessment of floods and its classification were investigated. The estimation of river-bed discharge was fulfilled by different methods. The Upper Tizsa basin river's channel stability was evaluated. It was investigated that rivers stability is connected with floods. The basin's rivers channels deformations were researched based on remote station materials and GIS. The main impact for the river stability caused by the most active floods . The methodical statements of mountain rivers classification were formulated and the classification of channels dividing into several type based on its high altitude was done. The main types of channellengthwere determined and main types for every of their altitude areas were found out. The dependences for different types of channel's hydromorphodynamic assessment were proposed. The floodplain modifications assessment with the aim of ecological estimation and complex researches of channel processes conditions development were done.
