In the last decades, natural hazards happened more and more frequently, causing considerable human and material losses for inhabitants of mountainous regions. In this relation, the problem of forecasting-warning the natural hazards for mountainous inhabited localities becomes imperative. However, at present study level a precise forecast for sheet flood, mud-flows, landslide, and landslide-rockfall is not yet feasible. In this context, an authentic warning of the mentioned processes seems to be very important and urgent for the safety of the population. This paper deals with that problem by analyzing the possibility of using geomorphologic methods for determining the safety degree of mountainous inhabited localities facing these hazardous processes. The processes have been examined in a deeply differential manner from the morphodynamic point of view to reveal the major factors which conduct to their appearance serving the basis for a good warning of the risk to the menaced settlements.
