- Skeiðarársandur (Icelandic pronunciation: [ˈsceiːðarˌauːrˌsantʏr̥]) is an Icelandic glacial outwash plain, a vast expanse of sand generated by the transport of debris by the Skeiðará and other rivers, whose flow is generated by the glacier and fed by the volcanic systems of Grímsvötn and Öræfajökull. The coastline of the Sandur is 56 km long (from Hvalsík to Hnappavallaós). From Skeiðarárjökull, the valley glacier of Vatnajökull, to the sea is 20–30 km. The Skeiðará was the most important obstacle in the construction of Iceland's Route 1. It was not until 1974 that it could be completely closed by a 904 m long bridge. This is currently the longest bridge in Iceland. It was temporarily destroyed by water masses and blocks of ice during the last major glacial outburst flood in 1996, triggered by an eruption of the Grímsvötn volcano, but was immediately restored. The outwash plain originated primarily as alluvial land, i.e. as an accumulation of sediments from the rivers. The sediments deposited here in the Holocene alone range from 100 to 200 km³. However, volcanic eruptions of the volcanic systems of Grímsvötn and Öræfajökull have added to these sediment deposits. The sediments are carried during glacial floods with the glacier water, which thaws during volcanic eruptions, but also through ash deposits. The outwash plain does not consist entirely of modern sediments. For example, there is also a cliff. In addition, through seismological experiments geologists discovered a 100–150 m deep valley in the bedrock below the modern sediment layers, which was probably milled out by glacial rivers of the Ice Age. Over the last 10,000 years, the outwash plain has grown at a speed of about 1 km³/century. (en)
- Skeiðarársandur è un ‘'sandur'’ islandese, cioè una vasta distesa di sabbia generata dal trasporto di detriti da parte di un fiume glaciale. In questo caso le inondazioni sono generate dal ghiacciaio Skeiðarárjökull ed alimentate dai sistemi vulcanici del Grímsvötn e Öræfajökull. Il risultato delle inondazioni è la formazione di un deserto di sabbia che si estende dal Vatnajökull, fino al mare per circa 1300 km2, facendo del Skeiðarársandur il più grande sandur del mondo. In particolare, il sandur ha una lunghezza tra i 20 ed i 30 km tra i ghiacciai a nord e l'oceano a sud, mentre il tratto di costa occupato è di 56 km di larghezza, sui meandri del fiume Skeiðará e di altri corsi d'acqua minori. La violenza dei flussi d'acqua nel caso di inondazione rappresenta una minaccia costante al Hringvegur, la grande strada nazionale che contorna tutta l'Islanda e che attraversa il Skeiðarársandur con un ponte di 904 m di lunghezza.

- Skeiðarársandur är en sandur (sandslätt) i republiken Island. Den ligger i regionen Austurland, i den södra delen av landet. Den uppstod främst som alluvial mark, det vill säga som en ansamling av sediment från floderna från glaciären Skeiðarárjökull. De sediment som har lagrats här enbart under holocen sträcker sig från 100 till 200 km³. (sv)
