Abstract

The new map of turbidity in the rivers of Ukraine has been created on the basis of a 50 year data set of sediment yield observed by the Hydrometeorological committee of Ukraine. The trends of sediment discharge have been established. The main causes of increasing or decreasing sediment discharge in rivers of the different regions of Ukraine (Ukrainian Polissia, Podilska and Prydniprovska highlands, Prychornomoska lowland, Donbas, Carpathian Mountains) are explained. Quantitative values of sediment erosion, transit and redeposition in different sections of the catchment system and its flood plain – riverbed complexes have been determined on the basis of a field experimental study of sediment redistribution within the cultivated slope – gully catchment – small river catchment system. The impact of erosion – accumulation processes on small river aggradation has been characterized.
