Studies from University of Turin Update Current Data on Geological Engineering

June 6, 2014



By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Current study results on Geological Engineering have been published. According to news reporting out of Turin, Italy, by VerticalNews editors, research stated, "The Maggiore Valley well field plays a fundamental role in supplying drinking water to a large territory of the Piedmont (north-western Italy). However, an increasing demand for water has led to the overexploitation of the groundwater resources."

Our news journalists obtained a quote from the research from the University of Turin, "This situation has caused a progressive drawdown of the piezometric level (locally, up to 0.8 m/year), a spatial reduction in the artesian zone, localised land subsidence and damage to wells. The main purpose of this study was the development of a groundwater flow model of the area for analysing the aquifer response to various pumping strategies. Initially, the groundwater flow simulation (achieved by the application of the MODFLOW code) was calibrated satisfactorily. Then, the groundwater response to four scenarios was simulated to explore the best option to mitigate the problem. In three of the scenarios, a withdrawal reduction of 110 l/s was simulated, whilst considering various relocation options for extraction within the well field. The fourth scenario simulated a withdrawal reduction of 150 l/s; this option also assumed a supplementary water supply from the Monferrato Aqueduct, located north of the study area. All the simulations provided an increase in the piezometric level; in some instances, up to 30 m. Based on these simulations, the most promising management strategy for the Maggiore Valley well field would seem to be the option using a supplementary feed from the Monferrato Aqueduct."

According to the news editors, the research concluded: "In this instance, the predicted piezometric level rise would be up to 25 m; this option also precludes the need for drilling additional wells."
