Il ciclo dell’acqua in Friuli

CAI Acqua.programma

ACQUA CHE SCORRE, SOMMERGE, DISTRUGGE E CREA

Un filo liquido che cuce insieme le meraviglie geologiche dell’Italia nord-orientale

 

  • Tagliamento e Fella: gli antichi percorsi tra Osoppo, Braulins, Venzone e Cavazzo (5-6 milioni di anni fa) mentre il Mar Mediterraneo prima andava in secca e poi tornava a riempirsi d’acqua.
  • L’ultimo milione d’anni: Mare Adriatico vs Mar Nero, lo spostamento progressivo dello spartiacque settentrionale.
  • Quando le acque del Tagliamento smisero di lambire Udine e il suo Colle.
  • L’ultima invasione dei ghiacci: archi morenici visibili e sepolti.
  • Il colpo di coda dell’ultimo glaciale. Il ritiro ‘definitivo’ dei ghiacciai e i tanti laghi ormai scomparsi.
  • Lo smantellamento accelerato dei rilievi friulani e i grandi ventagli di detriti torrentizi.
