Debris flows are considered as flows of highly liquefied sediments in mountain areas, usually triggered by intensive rainfall or snowmelt. They move rapidly through the transport channel or a gully and accumulate the debris material on a less slopping or flat areas, forming a debris fan. Often debris flows occur suddenly and could affect infrastructure as well as to influence human activity and life. This determines the growing need to deepen the research of the debris flows and to take into account the peculiarit...

Soil erosion is one of the most widely dispersed adverse geomorphological processes in a global scale. If it is not limited, it can change the topographic surface, reduce the slope stability and water retention capability, and thus increase the disposition for geomorphological hazards. Heavy rainfalls or intensive snowmelt are the main triggering factors for erosion, but the processes strongly depend on the topography, slope gradient, soil properties, vegetation cover and land use. The aim of the current research ...
