Abstract

Meltwater-related processes have long been recognized as first-order geomorphic mechanisms in both subglacial and proglacial environments. Among them, glacial outburst or jökulhlaups (the Icelandic term for “glacial flood”) represent short-term events (1-15 days, e.g. Snorrason et al., 2002) with major erosional and depositional impacts. They emanate either from the catastrophic drainage of glacially dammed lakes or from the drainage or collapse of subglacial reservoirs.
