Preliminary Study on the Snow-Melt for the Groundwater Recharge Estimated by an Advanced Meteorological Station

Abstract

In this study a preliminary procedure was analyzed in order to evaluate the Snow Water Equivalent through data derived from the sensors installed in the metereological station located upstream of the locality of Mascognaz—Ayas—Valle d’Aosta. The meteorological station has been developed within a research project covering various fields concerning climate change and space-time meteorological variability. Specifically we purpose to thoroughly study the transformations occurring inside the snowpack during the winter period and how it affects the groundwater recharge. Through the analysis of the parameters of humidity, temperature, precipitation and manual data, performed at least 3 days after the event, we have developed a methodology for the estimation of water availability before the melting process.
