Abstract

Electrical Resistivity Imaging (ERI) is a widely used tool in geophysical surveys for investiga- tion of various subsurface structures. In this study an ERI was conducted in collapse doline floors lo- cated in Divača karst, Slovenia. This group of collapse dolines in hinterland of River Reka ponors have floors inundated and flattened with loamy sediment. Collapse doline development and transforma- tion processes are discussed, and various characteristics and potential formation mechanisms of flat and loamy doline floors are considered. The loamy fills might reflect sedimentation of suspended ma- terial from floodwaters that inundated the lower parts of the collapse dolines, or could have originated in now-demolished cave passages on the slopes that were filled with finer material.
