This paper presents a methodology tuned to support the management of underground pipelines (sewer and aqueduct networks) in Rome, often threatened by sudden formation sinkholes related upward migration existing cavities. The integrates data coming from assessment susceptibility sinkhole advanced processing satellite-based SAR imagery. former, performed through multivariate logistic regression t...

Road subsidence and sinkhole failures due to shallow cavities formed by defective water main have increased in recent decades become one of the important research topics geotechnical engineering. The present paper numerically studies stability its associated failure mechanism ellipse-shaped cavity above mains using finite element limit analysis technique. For a wide range geometrical parameters...

We studied the motility of filamentous mat-forming cyanobacteria consisting primarily of Oscillatoria-like cells growing under low-light, low-oxygen, and high-sulfur conditions in Lake Huron's submerged sinkholes using in situ observations, in vitro measurements and time-lapse microscopy. Gliding movement of the cyanobacterial trichomes (100-10,000 μm long filaments, composed of cells ∼10 μm wi...
