Abstract
This paper describes an application of the geographic information system (GIS) technology to a ground stability assessment in the karst area of Dzerzhinsk, Russia. In the stability analysis, the groundwater level changes in the karst aquifer could cause suffosion sinkholes when the gravitational force was greater than the soil strength. The GIS technology was used to combine various data and to delineate the zones of potential gravitational collapse and suffosion collapse in the area.

Notes
In Russia, we distinguish (a) the slow process of suffosion into a karst cavity and (b) the quick collapse due to failure of a thin clay layer. We refer process (b) as "karst-suffosion".
