Insights into marine biological responses to Icelandic glacial outburst floods from remote sensing data
… W) at least since 1940. Jökulhlaup (glacial outburst floods) frequency has increased but their magnitude has decreased. This study examines jökulhlaup effects on the marine environment at the Gígjukvísl, Skaftá, and Kúðafljót estuaries. Remote sensing data integrated in situ, observational, …

Confronting Glacial Hazards: A Study of Disaster Impact and Community Adaptation to Glacial Lake Outburst Floods in Hunza, Pakistan
… face increasing risks from glacial lake outburst floods (GLOFs) with limited capacity to mitigate their impact and recover from repeated cycles of losses. This thesis looks at the Hassanabad settlement in Hunza, Pakistan which has faced five GLOF occurrences between 2019 and 2022 to study …

Quantifying environmental controls on the magnitude of glacial lake outburst floods and the resulting impacts to hydrology and geomorphology: Lago Cachet Dos, Patagonia, Chile
… the peak discharge of observed glacial lake outburst floods (GLOFs). Since April 2008, 20 GLOFs have initiated out of LC2, located on the eastern edge of the Northern Patagonia Icefield, Chile and flooded areas along the Rio Colonia- Rio Baker system. GLOF frequency has averaged 1-3 events …

Drowned landscapes of the Belgian Continental Shelf : implications for northwest European landscape evolution and preservation potential for submerged heritage
… resulting in catastrophic glacial lake outburst floods. A high-resolution depth-converted structure map of the pre-Quaternary surface combined with regional palaeogeographic reconstructions demonstrates that the late Middle to Late Pleistocene geological evolution of the Belgian …

Chilean glacial lake outburst flood impacts on dam construction
Four Glacial Lake Outburst Floods (GLOF) occurred in the Colonia Glacier (Northern Patagonia Icefield, Chile) from April 2008 to March 2009. Lago Cachet 2 emptied four times producing a maximum excess discharge in the downstream Rio Baker of about 2,500 m3/s. These events have occurred at the same …

Stratigraphy, Two-Dimensional Geometry and Internal Sedimentary Structure of Hyaloclastite Deposits in the Siða Formation, SE Iceland; Implications for Mechanisms of Emplacement
… was deposited by unconfined large-volume floods. Horizontal upper-plane bedding, large-scale (>2m) cross-beds, clinoforms (>5m), “floating clasts” and antidunes in the sheet-like units also infers the occurrence of glacier outburst floods since these features are documented in flood …

Fluvial Response to Intra-Canyon Lava Flows, Owyhee River, Southeastern Oregon
… at Dog Leg Bar. No deposits from catastrophic outburst floods resulting from lava dam failure have been found, supporting gradual incision rather than catastrophic failure of the dams. The lava dams were long and low, and the river commonly eroded around the dams, reducing the likelihood of …

Constraining the pathways and fluxes of subglacial meltwater beneath the palaeo-Antarctic Ice Sheet
… genesis has been attributed to catastrophic outburst floods, sourced from subglacial lakes during the Miocene. A similar process origin is proposed for the channels observed on the Antarctic continental shelf, formed through the drainage of relict subglacial lake basins, including some 59 …

Origin and stratigraphy of Holocene sediments, Souris and Des Lacs glacial-lake spillways, north-central North Dakota
… Lacs Valleys were formed by massive glacial-lake outburst floods at the end of the late Wisconsinan deglaciation. Five phases of drainage have been recognized with the first forming the Des Lacs Valley and the other four associated with drainage in the Souris Valley from different proglacial lakes …

Geomorphic Reconstruction and 3D Visualisation of a Tenth Century Volcanic Jökulhlaup at Sólheimajökull Glacier, South Iceland
Jökulhlaup (glacial outburst floods) present a recurring natural hazard to the inhabitants and infrastructure along Iceland’s south coast. The high-energy, debris-rich floods are capable of eroding, transporting and depositing vast quantities of sediment; and in some cases, can completely re-shape …
