Increased Glacier Melt Across Millennia to Hours Enhances Erosion and Sediment Export Processes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract Glacial erosion and sediment evacuation are key in shaping polar and mountain landscapes and influencing downstream ecological and social systems. The glacier dynamics and hydrology responsible for these processes are closely linked to hydrological and climatic (hydro‐climatic) conditions.

The 2015 Chileno Valley glacial lake outburst flood, Patagonia

Geomorphology, 2019
Glacial Lake Outburst Floods (GLOFs) have become increasingly common over the past century in response to climate change, posing risks for human activities in many mountain regions. In this paper we document and reconstruct the sequence of events and impact of a large GLOF that took place in December 2015 in the Chileno Valley, Patagonia.

Learning Lessons From Natural Disasters and the Derivation of Related Disaster Reduction Techniques [PDF]

, 2010
This paper describes the way how lessons that have been learned in the aftermath of a natural disaster can be analysed and subsequently structured in order to elicit inherent information important for making a lesson valid.

The Long‐Term C Footprint Trajectory and Emissions Attribution of a Large Boreal Reservoir (Paix Des Braves (Eastmain‐1), Québec)

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Hydropower is considered essential in meeting the increasing demand in low carbon energy in the context of climate change. Greenhouse gas emissions (GHG) by hydroelectric reservoirs have nevertheless become a major concern to the energy sector.

A Fluvio‐Lacustrine Environment Preserved in the Jezero Crater Inlet Channel, Neretva Vallis, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian fluvial valleys provide evidence for the surface flow of liquid water, making them a key target for rover‐based investigations of ancient habitability. The Mars 2020 Perseverance rover spent ∼85 sols exploring the Bright Angel formation, exposed across the floor of Neretva Vallis: the western inlet channel of Jezero crater.

Ice-margin and meltwater dynamics during the mid-Holocene in the Kangerlussuaq area of west Greenland [PDF]

, 2017
Land-terminating parts of the west Greenland ice sheet have exhibited highly dynamic meltwater regimes over the last few decades including episodes of extremely intense runoff driven by ice surface ablation, ponding of meltwater in an increasing number ...

UAV-based remote sensing of immediate changes in geomorphology following a glacial lake outburst flood at the Zackenberg river, northeast Greenland

Journal of Maps, 2020
Two detailed geomorphological maps (1:2000) depicting landscape changes as a result of a glacial lake outburst flood were produced for the 2.1-km-long section of the Zackenberg river, NE Greenland.

Modelling glacier-bed overdeepenings and possible future lakes for the glaciers in the Himalaya—Karakoram region [PDF]

, 2016
Surface digital elevation models (DEMs) and slope-related estimates of glacier thickness enable modelling of glacier-bed topographies over large ice-covered areas.

In-situ bathymetry and volume estimation of four glacial lakes in western Himalaya

Journal of Glaciology
Glacial lakes in the Himalayas have expanded significantly in recent decades, increasing the potential risk of outburst floods. However, limited field surveys and systematic assessments leave downstream communities vulnerable.
