For example, 11 sites in large rivers shows that the annual erosion of the banks visibly pulsate. By combining multi-temporal satellite images obtained ranks of annual erosion of the banks. Aggregated data and obtained statistical characteristics of the annual values of erosion of the banks: the average, standard deviation, coefficients of variation and asymmetry.
according to the author the profile of maximum possible erosion is considered as the results of engineering and hydrometeorological surveys in part of channel processes in modern normative documents. The article presents the classification of results to sediment processes: selecting target set of profiles of maximum erosion, maximum erosion profile in a given target, part of the profile, erosion in the plan, the demonstration of safety of erosion or lack of erosion.
