Parameterization of channel processes for their forecast estimation and diagnostics of hazardous manifestations

Abstract

The study considers parameterization principles of channel processes, which can be used to obtain quantitative or qualitative characteristics of various forms of channels and channel relief and hazardous manifestations of channel deformations. Channel parameters enable the development of hydromorphometric and hydrological–morphological relationships with the characteristics of channel process factors. The identification of measurable (direct) and integral (calculated and estimated) parameters is substantiated. The former parameters are taken to be the morphometric and morphologic characteristics of the channel and its forms (bends, bifurcations) and channel relief forms (ridges, riffles), the dynamic characteristics of the directions and rates of channel deformations.
