"The intensification of glacial melting strongly affects the quantity and seasonal distribution of water. Initially, the retreat of glaciers is going to increase the available water resources, but if precipitation doesn't compensate for the losses related to glacial retreat, the reduction of glacier volume will eventually reduce the amount of available water."The researchers proceeded to analyze a series of measurements based on many parameters related to climate, glaciers, and streamflow in order to compare this data with existing information. Although these studies have revealed a clear tendency toward a reduction in streamflow during the summer, the impact of melting glaciers on the annual flow remains unclear. "Many factors can have an influence on water quantity," explains Annina Sorg. "Precipitation level, evaporation, and even human interference on the hydrological cycle are all factors to consider."
The ACQWA project
ACQWA (Assessing Climate Impacts on the Quantity and quality of WAter, 2008-2013) is a European project which aims to quantify the influence of climatic change on river discharge and to analyse the impact on society and economy in mountainous regions such as the Alps, the Andes and the Tien Shan mountains. Coordinated by professor Martin Beniston and his team at the UNIGE, ACQWA gathers 35 research teams in Europe, Central Asia and South America and benefits from a 11 million swiss francs budget.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
