Karstification Processes in Haditha Vicinity, West Iraq

Iraqi Geological Journal, 2023
In the valley of the Euphrates River to the south of the Haditha city (West Iraq), the dissolution of the carbonate rocks which underlie residual soil gives rise to numerous sinkholes.

Using lidar data to analyse sinkhole characteristics relevant for understory vegetation under forest cover-case study of a high karst area in the dinaric mountains.

PLoS ONE, 2015
In this article, we investigate the potential for detection and characterization of sinkholes under dense forest cover by using airborne laser scanning data.

Hydro-Stratigraphic Conditions and Human Activity Leading to Development of a Sinkhole Cluster in a Mediterranean Water Ecosystem

Hydrology, 2021
Salento Peninsula (Apulia, southern Italy) is characterised by many active sinkholes, which represent the main geological hazard. The stretch of coastline between the village of Casalabate and Le Cesine wildlife reserve is highly affected, with a system ...

Efficiency of local minima and GLM techniques in sinkhole extraction from a LiDAR-based terrain model

International Journal of Digital Earth, 2019
The aim of this paper was to study reliable automated delineation possibilities of karst sinkholes using a LiDAR-based digital terrain model (DTM) with pixel-based classifications.

Multi-Temporal Satellite Interferometry for Fast-Motion Detection: An Application to Salt Solution Mining

Remote Sensing, 2020
Underground mining is one of the human activities with the highest impact in terms of induced ground motion. The excavation of the mining levels creates pillars, rooms and cavities that can evolve in chimney collapses and sinkholes.

Sinkhole risk mapping and early warning: the case of Camaiore (Italy)

Frontiers in Earth Science, 2023
Introduction: Sinkholes are ground collapses that can cause significant damage to infrastructure and buildings. Part of the risk represented by sinkholes is related to their abruptness and the difficulty in spotting in advance their exact location within

Non-Invasive Methodological Approach to Detect and Characterize High-Risk Sinkholes in Urban Cover Evaporite Karst: Integrated Reflection Seismics, PS-InSAR, Leveling, 3D-GPR and Ancillary Data. A NE Italian Case Study

Remote Sensing, 2020
Sinkholes linked to cover evaporite karst in urban environments still represent a challenge in terms of their clear identification and mapping considering the rehash and man-made structures.

Surface Deformations Resulting from Abandoned Mining Excavations

Energies, 2021
The occurrence of surface discontinuous deformations in post-mining areas is currently a significant and important problem, due to both the frequency of their occurrence and the threat they pose to public safety.

Effect of Sinkholes on Groundwater Resources in Arid and Semi-Arid Karst Area in Abarkooh, Iran

Environments, 2020
Despite protection measurements and their natural position, groundwater resources are very vulnerable due to natural and anthropogenic impacts. This is especially emphasized in karst arid and semi-arid zones, due to increased requirements for water ...
