Le rôle essentiel des débacles glacio-volcaniques dans l'évolution récente des côtes sableuses en voie de progradation du sud-est de l'Islande
South-eastern Iceland is characterized by extensive outwash plains (sandurs) supplied with bulky sediments from proglacial floods. The aggradation on sandurs is accordingly accompanied by fast shoreline progradation of beaches and barrier spits, especially after heavy glacier burst (Myrdalssandur, S...

Summary: | South-eastern Iceland is characterized by extensive outwash plains (sandurs) supplied with bulky sediments from proglacial floods. The aggradation on sandurs is accordingly accompanied by fast shoreline progradation of beaches and barrier spits, especially after heavy glacier burst (Myrdalssandur, Skeidararsandur). De grandes plaines fluvioglaciaires (sandurs) bénéficient d'apports sédimentaires considérables grâce à de puissants écoulements proglaciaires. En conséquence, l'aggradation des sandurs s'accompagne d'une progradation littorale rapide, notamment dans les endroits atteints par les grandes débâcles glacio-volcaniques (Myrdalssandur, Skeidararsandur). |
