25-year observations data of a scree slope in the Joekvara valley (Abkhasia)

Abstract

Long-term stationary observations were carried out on a scree formation within the wet tropics of Western Caucasus using repeated phototheodolite survey. The volume of debris coming to the scree apron has been found to bear a certain relationship to moisture regime and seismicity of the area. The input and output in the budget of gravitational flow (which feeds the scree apron) has been calculated and stadia changes in the longitudinal profile have been identified in the screes which rest on floodplain; the stages are presumably due to rivers action under changing moisture regime.
