An important, but largely neglected hydrogeological issue is the timing of mine water sampling during mining and after mine closure. Significant temporal and spatial changes in the “ageing“ of information, neglected effects of dynamic changes in the quality of mine water and its resources are causing severe degradation of information from mine water analyses and their possible misleading interp...
Groundwater pollution has become a worrisome phenomenon, mainly for aquifers underlying industrialized areas. In order to evaluate the risk of pollution, a model of the aquifer is needed. Herewith, we describe a quasi-tridimensional model, which we applied to a multilayered aquifer where a phreatic aquifer was coupled to a confined one by means of an aquitard. This hydrogeological scheme is oft...
Fracture and fault zones can channel fluid flow and transmit injection-induced pore pressure changes over large distances (>km), at which seismicity is rarely suspected to be human induced. We use seismicity analysis and hydrogeological models to examine the role of seismically active faults in inducing earthquakes. We analyze a potentially injection-induced earthquake swarm with three events a...
The Mar Piccolo basin is an internal sea basin located along the Ionian coast (Southern Italy), and it is surrounded primarily by fractured carbonate karstic environment. Because of the karstic features, the main continental water inflow is from groundwater discharge. The Mar Piccolo basin represents a peculiar and sensitive environment and a social emergency because of sea water and sediment p...
At the “Pašino vrelo” source, groundwater is exploited by means of wells which tap a carbonate aquifer of Badenian age. The natural quality of groundwater complies with the provisions of the Regulation on health and safety of drinking water. However, anthropogenic impacts in the form of microbiological pollution have been observed. Extensive hydrogeological investigations have been conducted in...
Climate warming and anthropogenic impact causes transformation of geocryological conditions in the river basins North-East Russia. Changes thickness active layer, configuration taliks, types landscapes other factors lead to water exchange processes between surface groundwater runoff. This is manifested seasonal redistribution components balance, accelerated melting aufeis, change ratio waters d...
Associated with the exploitation of metallic minerals in Europe during 20th century, several mining areas were abandoned without adequate environmental intervention. Furthermore, these lack studies to characterize impact pollution on hydrogeological system. The area surrounding tungsten mine Regoufe, northern Portugal, is one such exploited Second World War. accumulation sulfide-rich tailings m...
Jupiter’s Great Red Spot (GRS) has been observed in sufficient detail that we can use it to determine properties of the jovian atmosphere that cannot otherwise be found. These properties include: the potential vorticity of the GRS and its neighboring zonal jet streams, the shear imposed on the GRS by the jet streams, and the vertical entropy gradient (i.e., Rossby deformation radius). We show t...
