Identification of glacial meltwater runoff in a karstic environment and its implication for present and future water availability

Finger, D. ; Hugentobler, A. ; Huss, Matthias ; Voinesco, A. ; Wernli, Heini ; Fischer, D. ; Weber, E. ; Jeannin, Pierre-Yves ; Kauzlaric, M. ; Wirz, A. ; Vennemann, T. ; Hüsler, F. ; Schädler, B. ; Weingartner, R.

Glaciers all over the world are expected to continue to retreat due to the global warming throughout the 21st century. Consequently, future seasonal water availability might become scarce once glacier areas have declined below a certain threshold affecting future water management strategies. Particular attention should be paid to glaciers located in a karstic environment, as parts of the...

Density assumptions for converting geodetic glacier volume change to mass change

Huss, Matthias

In: The Cryosphere, 2013, vol. 7, no. 3, p. 877–887

The geodetic method is widely used for assessing changes in the mass balance of mountain glaciers. However, comparison of repeated digital elevation models only provides a glacier volume change that must be converted to a change in mass using a density assumption or model. This study investigates the use of a constant factor for the volume-to-mass conversion based on a firn compaction model...

Seismic activity and surface motion of a steep temperate glacier: a study on Triftgletscher, Switzerland

Dalban Canassy, Pierre ; Faillettaz, Jérome ; Walter, Fabian ; Huss, Matthias

In: Journal of Glaciology, 2012, vol. 58, no. 209, p. 513-528

The tongue of Triftgletscher, Switzerland, is particularly susceptible to major break-off events due to its steep slope. In order to detect precursors of such an event, we monitored the local seismic activity and detected 2426 icequakes with sources located in an area ranging between 2050 and 2350 m a.s.l. Events triggered by cracks and icefalls were recorded, but no precise distinction between...

Distributed ice thickness and volume of all glaciers around the globe

Huss, Matthias ; Farinotti, Daniel

In: Journal of Geophysical Research, 2012, vol. 117, p. F04010

A new physically based approach for calculating glacier ice thickness distribution and volume is presented and applied to all glaciers and ice caps worldwide. Combining glacier outlines of the globally complete Randolph Glacier Inventory with terrain elevation models (Shuttle Radar Topography Mission/Advanced Spaceborne Thermal Emission and Reflection Radiometer), we use a simple dynamic model to...

Extrapolating glacier mass balance to the mountain range scale: the European Alps 1900–2100

Huss, Matthias

In: The Cryosphere Discuss., 2012, vol. 6, p. 1117-1156

This study addresses the extrapolation of single glacier mass balance measurements to the mountain range scale and aims at deriving time series of area-averaged mass balance and ice volume change for all glaciers in the European Alps for the period 1900–2100. Long-term mass balance series for 50 Swiss glaciers based on a combination of field data and modelling, and WGMS data for glaciers in...

Potential climatic transitions with profound impact on Europe: review of the current state of six ‘tipping elements of the climate system’

Levermann, Anders ; Bamber, Jonathan L. ; Drijfhout, Sybren ; Ganopolski, Andrey ; Haeberli, Winfried ; Harris, Neil R. P. ; Huss, Matthias ; Krüger, Kirstin ; Lenton, Timothy M. ; Lindsay, Ronald W. ; Notz, Dirk ; Wadhams, Peter ; Weber, Susanne

In: Climatic Change, 2011, vol. 110, no. 3-4, p. 845-878

We discuss potential transitions of six climatic subsystems with large-scale impact on Europe, sometimes denoted as tipping elements. These are the ice sheets on Greenland and West Antarctica, the Atlantic thermohaline circulation, Arctic sea ice, Alpine glaciers and northern hemisphere stratospheric ozone. Each system is represented by co-authors actively publishing in the corresponding field....

Evaluating the effect of snow and ice melt in an Alpine headwater catchment and further downstream in the River Rhine

Junghans, Nadine ; Cullmann, Johannes ; Huss, Matthias

In: Hydrological Sciences Journal, 2011, vol. 56, no. 6, p. 981–993

Le régime hydrologique des bassins versants amont glaciaires dans les Alpes est essentiellement caractérisé par la fonte de neige et de glace. Les hauts bassins versants alpins influencent les débits du Rhin loin en aval. Avec le changement climatique, des faibles débits seront possibles en période estivale en raison de la forte diminution de la fonte de neige et de glace. Cette étude...

Runoff evolution in the Swiss Alps: projections for selected high-alpine catchments based on ENSEMBLES scenario

Farinotti, Daniel ; Usselmann, Stephanie ; Huss, Matthias ; Bauder, Andreas ; Funk, Martin

In: Hydrological Processes, 2011, vol. 25, p. -

The Alps are often referred to as the ‘water tower of Europe’. In Switzerland, many branches of the economy, especially the hydropower industry, are closely linked to and dependent on the availability of water. Assessing the impact of climate change on streamflow runoff is, thus, of great interest. Major efforts have already been made in this respect, but the analyses often focus on...

Present and future contribution of glacier storage change to runoff from macroscale drainage basins in Europe

Huss, Matthias

In: Water Resources Research, 2011, vol. 47, p. W07511

The contribution of glaciers to runoff from large-scale drainage basins in Europe is analyzed for the major streams originating in the Alps: Rhine, Rhone, Po, and Danube. Detailed information on glacier storage change is available from monthly mass balance data of 50 Swiss glaciers for the period 1908–2008. Storage changes are extrapolated to all glaciers in the European Alps. By comparing...
