Leakage properties and the potential for land subsidence due to groundwater withdrawal from a multi-aquifer water supply system were investigated by applying leaky type curve and one dimensional consolidation models to drawdown data that were obtained during a pumping test experiment in an aquifer-aquitard system. The producing aquifer has transmissivity and storativity values of 5.3 X 10" m s"...

A gas blowout during an unauthorized well drilling occurred on June 9, 2020 at the Rome-Ciampino boundary periphery of Colli Albani quiescent volcano. This zone hosts a shallow confined gas-pressured aquifer, which recently produced further three blowouts. Dangerous atmospheric CO2 and H2S concentrations killed some birds, 12 families were evacuated. The helium isotopic composition indicates th...

[1] The generalized radial flow approach to hydraulic test interpretation uses the flow dimension to describe the change in flow area versus radial distance from the borehole. The flow dimension of a hydraulic test may reflect several characteristics of the hydrogeologic system, including heterogeneity, boundaries, and leakage. We show that a radial flow system with a linear, constant-head boun...
