Processes and Features of Subsidence Dolines (Sinkholes)

Abstract

This study deals with the processes of subsidence dolines. These processes contribute to the understanding of the characteristics of karst areas and the relation between dolines and their environment. For this, several hundred dolines of various karst areas were studied. Investigations included measurements of doline size and processes (for example mass movements), the mapping of their morphology and processes, observation and tracking of some processes (for instance water inflow). Laboratory experiments were carried out, and we had VES measurements performed to obtain data on their sediments. The processes of dolines with various development phase were distinguished. The processes of developed dolines were classified according the site of their effect which may be present in the environment, on the side slope, on the floor, on the cover below the floor and in the bedrock. The processes were also put into groups based on their direction. It was established that the degree of supplier and transporting away processes and their value compared to each other controls doline size, while the denudation of the doline slope and the accumulation on its floor influences doline shape.

Landscape Evolution in Glacier Valleys of Glaciokarsts

“…Recent, presently developing dissolution dolines are smaller than the previous ones, which can be regarded as features of postglacial age [26]. Above the tree line, Recent, presently developing dissolution dolines are smaller than the previous ones, which can be regarded as features of postglacial age [26]. Above the tree line, schachtdolines are more and more widespread instead of these features [3,17,27].…”

A General Description of Karst Types

“…They are also genetically diverse thus there are of ponor caves, spring caves, through caves, foot caves, etc. [12,19,22]. They often have an important role in the development of karst types (hypogene karst).…”
