Geotechnical monitoring and modeling of suffusion sinkhole formation in urban areas

Monitoring the state of natural and technical systems in urban areas using remote methods allows not only to fix zones of anomalies of various genesis, but also to create opportunities for predicting areas of suffusion cavities occurrence and their growth rate before appearance on the surface. To determine the scenarios of sinkhole formation, a physical hydrogeological modeling was carried out. Non-destructive testing methods may play an important role in the localization of potentially dangerous areas with disturbed physical and mechanical properties of natural and technical systems. The revealed regularities make it possible to carry out predictive assessments and identification of hazardous processes.
