The risk of exposure to droughts has increased<\/strong> in recent years, extending even to areas where they were not previously experienced, such as the Alpine region. The sector most directly affected by drought is agriculture<\/strong>, since the entire production chain is affected, but the hydro-electric power <\/strong>sector is also affected, both in terms of production and planning.<\/p>\n\n

The\u00a0Snow Water Equivalent<\/strong>\u00a0(SWE), i.e., the amount of water available as the snowpack melts, is a key variable in assessing the available water supply in mountain basins<\/strong>.<\/p>\n\n

Radarmeteo <\/strong><\/a>\u00a0and\u00a0Hypermeteo<\/strong><\/a>\u00a0 have developed a new system to provide high resolution and accurate SWE data.<\/strong>\u00a0They are obtained through algorithms fed from all available observational sources (on-site measurements from snow gauges, satellite measurements and those from meteorological reanalysis datasets), spatialised using different statistical procedures and integrated into a cryohydrological model.<\/p>\n\n

This makes it possible to provide a constantly updated dataset<\/strong> relating to this variable, in order to monitor and improve basin management<\/strong>.<\/p>\n\n

CASE STUDY<\/strong><\/p>\n\n

The Alpine regions of Veneto<\/strong>,\u00a0Piedmont<\/strong>\u00a0and\u00a0Lombardy<\/strong>\u00a0were selected by the SNOWtoWATER<\/strong>\u00a0project \u2013 funded by the European Space Agency – for the evaluation of the proposed method. Four domains in the Alps were considered (Fig. 1), at a resolution of 200 m, and the model simulated the snow seasons (September to May) 2018\/19-2019\/20-2020\/21-2021\/22 in hourly steps.<\/p>\n\n

Model runs with the reanalysis dataset showed a better correlation with observations than did the forecast dataset<\/strong>, as the former is based on meteorological observational data whereas the latter has a higher level of uncertainty due to model drift.<\/p>\n\n

The results obtained in the case study made it possible to replicate the system on a national level<\/strong>\u00a0(Fig. 2), in order to share the SWE datasets with major national energy and water operators.<\/p>\n\n

CONCLUSIONS AND FUTURE DEVELOPMENTS<\/strong><\/p>\n\n

This system offers an innovative solution for measuring SWE<\/strong> because it combines several data sources within a flexible and easily upgradable system.<\/p>\n\n

At the same time, new data validation<\/strong>, spatialisation<\/strong> and assimilation<\/strong> procedures will continue to be developed, with the aim of obtaining an increasingly accurate and reliable representation of water resources<\/strong> throughout Italy.<\/p>\n\n
