Description :
This paper examines, first, physical properties of landslide materials and dynamics of landslide processes using such geomorphometric attributes as length of the landslide mass, the relative altitude and the area of the mass. Special attention is paid to geology because morphometric characteristics of landslide mass differ with lithology. Next, to find the site conditions favorable for landslide occurence, the relation between lanslide volume and relief magnitude is examined. Relief magnitude, which is expressed by the dispersion of altitude distributed over a specific square sample space, is a geomorphometric attribute that can now be calculated easily from DEMs.
