Description :
This paper presents new evidence for spatial and temporal changes in intraglacial floodwater routing during jökulhlaups (glacial outburst floods); secondly, it identifies and explains the mechanisms controlling the position and morphology of supraglacial jökulhlaup outlets; and finally, it presents a conceptual model of the controls on supraglacial outbursts. Field observations are presented from 2 Icelandic glaciers.
