Abstract

A great number of lichenometric observations on breakstone and mammock slopes showed multiple changes of gravitational slope processes intensity. There are 11-, 14-, 22-, 45-, 80-, 142- and 283-year periods of such changes. The model of gravitational morpholithodynamics is worked out. It allows to analyze the impact of climatic factors and to forecast the changes of slope processes in the near future. Lichenometric approach to evaluation of upcast and downcast lithodynamic flow balance on local morphosculptures of gravitational type is discussed.
