Abstract—Contributions of structural, geomorphologic, and lithological factors to karst and suffosion devel-
opment in the Lower Oka region are determined from the combined geological and geomorphologic analysis
of the modern and buried relief, the neotectonic structure, and the distribution of karst and suffosion forms.
