Panta Rhei-Everything Flows: Change in hydrology and society-The IAHS Scientific Decade 2013-2022

Bettina Schaefli, Eva Jakab Toth, Harshit Gupta

The new Scientific Decade 2013-2022 of IAHS, entitled Panta RheiEverything Flows, is dedicated to research activities on change in hydrology and society. The purpose of Panta Rhei is to reach an improved interpretation of the processes governing the water ...

EVAPOTRANSPIRATION: A PROCESS DRIVING MASS TRANSPORT AND ENERGY EXCHANGE IN THE SOIL-PLANT-ATMOSPHERE-CLIMATE SYSTEM

Marc Parlange, Gabriel George Katul, Chad Higgins

The role of evapotranspiration (ET) in the global, continental, regional, and local water cycles is reviewed. Elevated atmospheric CO2, air temperature, vapor pressure deficit (D), turbulent transport, radiative transfer, and reduced soil moisture all impa ...

A global picture of the first abrupt climatic event occurring during the last glacial inception

Jérôme Chappellaz

The last deglaciation was marked by large, hemispheric, millennial-scale climate variations: the Bølling-Allerød and Younger Dryas periods in the north, and the Antarctic Cold Reversal in the south. A chronology from the high-accumulation Law Dome East Ant ...

Energy dissipation downstream of Piano Key Weirs – Case of study of Gloriettes Dam (France)

Martin Peter Bieri, Matteo Paolo Elia Antonio Federspiel

The Gloriettes concrete arch dam in the French Pyrenees showed a deficit of 80 m3/s for the new design flood of 150 m3/s. To address the problem, a Piano Key Weir (PKW) as an additional spillway was designed. The existence of a geotechnically unstable zone ...

The economic impact of climate change and adaptation strategies in the water sector

Marc Vielle, Camille Gonseth, Anne-Kathrin Faust

In the near future, Switzerland is predicted to be affected by climate change, that is bound to impact both water demand and water supply in multiple ways. While water demand by households, firms and agriculture increases, water supply decreases (ProClim a ...

Integrated Approach for the Intensification of Heterogeneous Catalytic Processes

Lioubov Kiwi, Rocio Micaela Crespo Quesada

The integrated approach for the design of solid catalysts for process intensification is presented addressing simultaneously different levels of scale and complexity involved in the development starting from the molecular/nano-scale of the active phase opt ...

Hydrological Importance and Water Quality Treatment Potential of a Small Freshwater Wetland in the Humid Tropics of Costa Rica

Manon Bachelin

Rapid increases in population and growing food demand are causing widespread deterioration of tropical wetlands globally, and an increased focus on the role and function of these imperiled ecosystems is required. Objectives of this study were to investigat ...

Seasonal trends and temperature dependence of the snowfall/precipitation-day ratio in Switzerland

Martine Rebetez, Gaëlle Serquet

This paper analyzes the proportion of snowfall days relative to precipitation days, in order to assess the impact of changing temperatures on snowfall, while minimizing the impact of variations in precipitation frequency and intensity. We analyzed the rati ...

Response of terrestrial N2O and NOx emissions to abrupt climate change

Jed Oliver Kaplan, Mirjam Pfeiffer

Being a potent greenhouse gas, N2O emitted by the terrestrial biosphere during abrupt climate change events could have amplified externally forced warming. To investigate this possibility, we tested the sensitivity of terrestrial N2O emissions to an abrupt ...

On the enzymatic activity of catalase: an iron L-edge X-ray absorption study of the active centre

Majed Chergui

Catalase and methaemoglobin have very similar haem groups, which are both ferric, yet catalase decomposes hydrogen peroxide to water and oxygen very efficiently, while methaemoglobin does not. Structural studies have attributed this behaviour to their diff ...
