Abstract

The article raises the issue of development of current mass movements in the escarpment zone of river valley. The study area is located in Lower Vistula Valley near Świecie. The area is distinguished from its neighboring areas by the direct influence of the river on a slope, resulting inter alia to the development of landslides. They constitute an important process of shaping this slopes, occupying 30 percent of its surface. The paper presents an analysis of passive and active factors affecting the development of local landslides. The analysis has taken into consideration the factor of groundwater, geological settings and river erosion impacts.
