Hillsborough County, Florida, is a karst region that is heavily urbanized, yet no study has been undertaken measuring the degree of human disturbance. Van Beynen and Townsend (2005) created a hierarchical and standardized disturbance index specifically designed for karst environments. To address the problem of determining human disturbance in the county, the above index was successfully applied...

In a mature karstic system, the realisation of galleries using the methodology of railway tunnel boring machine (TBM) involves particular problems due to the high risk of interference with groundwater (often subject to remarkable level variations) and with cavities and/or thick fill deposits. In order to define groundwater features it is necessary to investigate both hydrodynamic and karstifica...

Rock varnish, erosional grooves, and well-developed cavernous weathering phenomena occur in close association on a small biotite-monzogranite nunatak in the Northern Foothills region, Northern Victoria Land, Antarctica. The grooves, similar in appearance to the ‘rinnenkarren’ described in the karst literature, are developed on steeply inclined (>35°) bedrock surfaces while the rock varnish occu...

In the framework of a collaboration between INAIL and University Salento, an indoor radon survey in 54 buildings belonging to UniSalento (Southeast Italy) was carried out. The monitored differ by type, construction period, materials, etc., are located area with morphology characterized mainly marls, calcareous calcarenites (karst area). sample includes 963 rooms at different floors: it consists...
