Automatic Segmentation of Sinkholes Using a Convolutional Neural Network
Earth and Space Science, 2022 Sinkholes are the most abundant surface features in karst areas worldwide. Understanding sinkhole occurrences and characteristics is critical for studying karst aquifers and mitigating sinkhole‐related hazards.

A Chronological Database about Natural and Anthropogenic Sinkholes in Italy
Geosciences, 2022 Sinkholes are a widespread geological hazard, typical of karst lands, where they generally originate as collapse features related to presence of underground voids.

Changes in the sediment microbial community structure of coastal and inland sinkholes of a karst ecosystem from the Yucatan peninsula. [PDF]
Sci Rep, 2022 The karst underground river ecosystem of Yucatan peninsula is composed of cave systems and sinkholes. The microbial diversity of water from this underground river has been studied, but, structure of the microbial community in its cave sediments remained ...

Experimental assessment of the relationship between rainfall intensity and sinkholes caused by damaged sewer pipes [PDF]
Natural Hazards and Earth System Sciences, 2020 In several countries, the rising occurrence of sinkholes has led to severe social and economic damage. Based on the mechanism of sinkhole development, researchers have investigated the correlation between rainfall intensity and sinkholes caused by ...

Pattern-Based Sinkhole Detection in Arid Zones Using Open Satellite Imagery: A Case Study Within Kazakhstan in 2023 [PDF]
SensorsSinkholes are significant geohazards in karst regions that pose risks to landscapes and infrastructure by disrupting geological stability. Usually, sinkholes are mapped by field surveys, which is very cost-intensive with regard to vast coverages.

Sinkholes and uvalas in evaporite karst: spatio-temporal development with links to base-level fall on the eastern shore of the Dead Sea [PDF]
Solid Earth, 2019 Enclosed topographic depressions are characteristic of karst landscapes on Earth. The developmental relationship between depression types, such as sinkholes (dolines) and uvalas, has been the subject of debate, mainly because the long developmental ...

JCMS: Journal of Cinema and Media Studies, 2019 Sinkholes are among the most distinctive features in karst lands and represent the most direct connection in karst between the ground surface and the subterranean world (Fig. 1). An alternative word is doline, derived from the Slav term which indicates generically a depression but is actually used to designate a variety of surface landforms in karst ...

Bacteria Halotolerant from Karst Sinkholes as a Source of Biosurfactants and Bioemulsifiers [PDF]
Microorganisms, 2022 Halotolerant bacteria with biosurfactant (BS) and bioemulsifiers (BE) activity can coexist in Karstic sinkholes with marine influence. Two sinkholes in the Yucatan peninsula were selected to isolate bacteria with BE and BS activity stable in NaCl.

Bryophyte diversity in karst sinkholes affected by different degrees of human disturbance
Acta Societatis Botanicorum Poloniae, 2019 The diversity of bryophytes in karst sinkholes has received little attention, and these habitats probably play a crucial role as refugia. In this study, bryophyte diversity affected by different levels of human disturbance in five karst sinkholes was ...
