“…The evolution and development of subsidence dolines is also influenced by other impacts such as water flows, earthquakes, meteoric water, the fluctuation of karstwater level and groundwater level, the burden due to vehicle traffic, vibration and anthropogenic activity and pore water pressure [7,15,[17][18][19][20][21][22][23][24][25].…”

“…On the Mecsek Karst, a surface section with a doline density of 380 doline /km 2 occurs [26]. Their development rate (especially that of dropout dolines) is high thus, it can be 0.2 km -2 year -1 on Kentucky Karst [24], while in Eastern Tennessee a rate of 0.64 km -2 year -1 [27] is also characteristic. They are mostly young features, their life expectancy is also short, maybe some thousand years.…”

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.

“…According to model experiments [40], the material rearrangement in the cover can be vertical and with horizontal suffosion, which is followed by compaction. Material rearrangement in the cover may happen by the collapse of the cavities of the cover [29,31], and/or by the detachment of particles from the cover ceiling if the pressure of pore water increase in the cover [41], or if the water level decreases in the cover and in its cavity and this results in the increase of hydrostatic pressure, which causes the failure and thus, the collapse of the material above the cavity of the cover [31,41,42]. Material transport in the cover may be reworked and transported into the bedrock.…”

“…Its development rate is 0.055 doline/km 2 /year [29]. A greater rate is specific of the area of the Western Pennyroyal karst of Kentucky where the development rate of dropout dolines was 0.2 dropout doline km −2 year −1 between 1971 and 1991 [41]. A minimal rate of 0.11 doline km −2 year −1 was reported from Florida by Beck [59] and 0.04-0.64 doline km −2 year −1 from Eastern Tennessee by [60].…”

Development Environments and Factors of Subsidence Dolines

This study describes the development environments of subsidence dolines based on literary data (development environments create favorable conditions for the local denudation of superficial deposit and thus, for the development of depressions). Development environments are the inclination of the bearing surface, the secondary porosity of the bedrock, the characteristics of the cover, water influx into the cover, karstwater and groundwater, melting permafrost, and anthropogenic activity. These may become optimal when controlled by various geological, geomorphological, and climatic factors. Development environments may be qualitative (there is doline development in case of its presence) and quantitative (doline development occurs in case of suitable quantitative values). The development environment groups of subsidence dolines are environment groups independent of water level, environment groups dependent on water level, and anthropogenic environment groups. In the case of an environment group independent of water level, surface morphology, cover characteristics, geomorphic evolution, and water supply are determining, while in case of an environment group dependent of water level, subsurface water level and its fluctuations and the characteristics of rainfalls interrupting dry seasons are crucial. Anthropogenic impacts mainly affect doline development through water balance.

“…The study of carbonate cave deposits through petrology and geochemistry of stalactitic and travertine deposits is an established field of research, as are hydrological studies of karst terrains, hydrodynamics of fluvial clastic deposits within subterranean caves and buried karst voids (Loucks, ; Loucks & Mescher, ; Klimchouk, ; Herman et al ., ). However, few studies have been made of clastic sinkhole fills, either subaerial (Currens et al ., ) or subaqueous (Klimchouk & Andrejchuk, ). Almost all studies of clastic sinkhole fills have focused on collapse breccia (Broughton, ) resulting from sinkhole deepening or related roof collapses that accompanied lateral expansions into cavernous voids (Eliassen & Talbot, ).…”

Incipient vertical traction carpets within collapsed sinkhole fills

Small vertically oriented traction carpets are reported from the collapsed sandy fills of 100 m deep Devonian limestone sinkholes underlying the Lower Cretaceous Athabasca oil sands deposit in north‐eastern Alberta, Western Canada. Dissolution of 100 m of underlying halite salt beds caused cataclysmic collapse of the sinkhole floors and water saturated sinkhole sand fills to descend very rapidly. Turbulent currents flushed upper sinkhole fills of friable sandstone blocks and disaggregated sand and quartz pebble for tens of metres. Laminar deposits with inverse grading accumulated as many as six to eight curvilinear entrained pebble streaks, 10 to 30 cm long, vertically impinged against the sides of descending collapse blocks. These deposits were initiated as vertically oriented early stage traction carpets that interlocked fine sand grains and inversely graded overlying pebbles entrained below the dilute overlying turbulent flows. Vortexes that flushed these sinkhole fills and induced these depositional processes may have lasted only seconds before the very rapid descents abruptly halted. Some of the fabrics were suspended vertically in‐place and preserved from unlocking and obliteration. These small fabrics provide insight into the instability and ephemeral character of the transition from strong gravity‐driven grain falls to very early stages of traction carpet formation. These short‐lived deposits of very thin sand layers resulted from sufficient incipient frictional freezing that grain interlocking overcame, however briefly, the strong gravity drives of the vertical falls that would have otherwise dispersed grains and obliterated any organized fabric patterns. Tenuous frictionally locked grains were also suspended at the centres of hyperbolic grain fall flows that briefly developed between turbulent flow eddies, some of which were fortuitously preserved. Some of these suspended grain locking zones passed downward onto the relatively more stable surfaces of the rapidly descending block surfaces. The morphogenesis of these early stage traction carpets differ from more fully developed deposits elsewhere because of their short‐lived transport, dynamic instability and vertical orientation.
