Abstract

The main methodical approaches of riverbed processes forecasting under increase/decrease of water content due to climate changes and human impact are analyzed. The authors estimate the workability of hydrologic-morphologic dependences. The relations of radii and wavelengths of meanders with water discharges are most elaborated, while such common correlations for braded channels are practically absent. The possibilities of the QI-diagrams use for the evaluation of the riverbed transformation due to changes of the factors affecting channel processes are shown. The main difficulties in further forecasting are formulated, in particular the lack of more or less reliable scenario of water content changes; the important aims are the validation of the most reasonable scenario, its application for channel processes forecasting for certain rivers, further estimation of hazardous consequences of channel processes.
