In order to understand the gravity process of recent landslides it is important to explore fossil
landslides, which occurred during the near and distant geological past. Fossil, especially sub recent
landslides can show us unstable and potentially dangerous areas to which we should pay attention
today. A unique insight into different slope processes in nature is certainly Rebrnice area, where you
can research the characteristics of the fossil landslides while observing the activity of the recent
landslidess. The slope deposit in the Rebrnice area were described and mapped by many authors but
nobody has covered the transport mechanisms and depositional processes of quaternary slope deposit
in detail. This doctoral thesis presents the study of slope deposit elaborated with the geologicalgeomorphological
approach. With the visual interpretation of the shaded digital elevation model and
indicator of surface roughness, which are calculated from the data of airborne laser scanning in the
combination of geological mapping, we can in most cases clearly identify the form of the prevalence
and surface characteristics of individual sedimentary bodies. On the basis of the lithological,
stratigraphic and architectural characteristics of the slope deposit 16 facies were separated, indicating
the final articles of diverse sedimentary processes within complex and often interlaced and
interdependent transport mechanisms. Results described in this work, and a comprehensive review of
the available data and literature have made it possible to understand the transport mechanisms and the
depositional processes of quaternary slope deposit in the Rebrnice area and thereby allow new insight
into slope movement throughout the northern area of the Vipava Valley.
