The presence of high and steep mountains near the\nsea on the central and south-eastern coast, causes an East-\nWest precipitation gradient in autumn especially, due to hot\nand moist currents coming from Africa. Soil structure and\nutilization make this area highly vulnerable to flash flooding\nand landslides. The specific purpose of this work is to\nprovide a description of the heavy rainfall phenomenon on a\nstatistical basis. The analysis mainly focuses on i) the existence\nof trends in heavy rainfall and ii) the characterization\nof the distribution of extreme events. First, to study possible\ntrends in extreme events a few indices have been analyzed by\nthe linear regression test. The analysis has been carried out\nat annual and seasonal scales. Then, extreme values analysis\nhas been carried out by fitting a Generalized Pareto Distribution\n(GPD) to the data. As far as trends are concerned,\ndifferent results are obtained at the two temporal scales: significant\ntrends are obtained at the seasonal scale which are\nmasked at the annual scale. By combining trend analysis\nand GPD analysis, the vulnerability of the study area to the\noccurrence of heavy rainfall has been characterized. Therefore,\nthis work might support the improvement of land use\nplanning and the application of suitable prevention systems.\nFuture work will consider the extension of the analysis to all\nSardinia and the application of statistical methods taking into\naccount the spatial correlation of extreme events."@en ; prodottidellaricerca:prodottoDi modulo:ID8164 , istituto:CDS050 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA9234 . @prefix parolechiave: . prodotto:ID31570 parolechiave:insiemeDiParoleChiave . ns11:ID57823 pubblicazioni:rivistaDi prodotto:ID31570 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID31570 .
