Detailed inundation modelling was conducted along a 100 km long transnational section of the Meuse River (in Belgium and The Netherlands), using very similar models for the whole computation (2D unsteady models). As a result, damping of the flood waves could be quantified and the possible relevance of using a steady-state approach could be assessed. The new detailed 2D hydraulic simulations have demonstrated that only a very limited damping of the flood waves occurs along the simulated reaches. From the perspective of the variation in peak discharge, the study concludes that running the hydraulic model in steady mode makes perfectly sense. Nonetheless, the steady computations lead to extensive overestimations of the inundated extent and of the stored volume in the floodplains. The 2D unsteady model constitutes also a tool of primary interest, which is readily available to design and evaluate protection measures for flood-prone areas such as in the city of Liege. [less ▲]

Role of sea ice in global biogeochemical cycles: Emerging views and challenges

Observations from the last decade suggest an important role of sea ice in the global biogeochemical cycles, promoted by (i) active biological and chemical processes within the sea ice; (ii) fluid and gas exchanges at the sea ice interface through an often permeable sea ice cover; and (iii) tight physical, biological and chemical interactions between the sea ice, the ocean and the atmosphere. Photosynthetic micro-organisms in sea ice thrive in liquid brine inclusions encased in a pure ice matrix, where they find suitable light and nutrient levels. They extend the production season, provide a winter and early spring food source, and contribute to organic carbon export to depth. Under-ice and ice edge phytoplankton blooms occur when ice retreats, favoured by increasing light, stratification, and by the release of material into the water column. In particular, the release of iron – highly concentrated in sea ice – could have large effects in the iron-limited Southern Ocean. The export of inorganic carbon transport by brine sinking below the mixed layer, calcium carbonate precipitation in sea ice, as well as active iceatmosphere carbon dioxide (CO2) fluxes, could play a central role in the marine carbon cycle. Sea ice processes could also significantly contribute to the sulphur cycle through the large production by ice algae of dimethylsulfoniopropionate (DMSP), the precursor of sulfate aerosols, which as cloud condensation nuclei have a potential cooling effect on the planet. Finally, the sea ice zone supports significant ocean-atmosphere methane (CH4) fluxes, while saline ice surfaces activate springtime atmospheric bromine chemistry, setting ground for tropospheric ozone depletion events observed near both poles. All these mechanisms are generally known, but neither precisely understood nor quantified at large scales. As polar regions are rapidly changing, understanding the large-scale polar marine biogeochemical processes and their future evolution is of high priority. Earth system models should in this context prove essential, but they currently represent sea ice as biologically and chemically inert. Paleoclimatic proxies are also relevant, in particular the sea ice proxies, inferring past sea ice conditions from glacial and marine sediment core records and providing analogs for future changes. Being highly constrained by marine biogeochemistry, sea ice proxies would not only contribute to but also benefit from a better understanding of polar marine biogeochemical cycles. [less ▲]

Impacts of future floods and low flows on the economy in the Meuse basin

in Dewals, Benjamin; Fournier, Maïté (Eds.) Transboundary Water Management in a Changing Climate (2013)

Climate change in Western Europe is projected to result in more humid winters and drier summers. Further, the sverities of floods and low flows are assumed to increase in the future. The impacts of these events could lead to adverse consequences on the economy. Given this framework, within the AMICE project, the impacts of future floods and low flow will be analyzed. A flood risk analysis in the Meuse basin is conducted taking into account future climate scenarios. Further, the impacts of future droughts and low flows are analyzed for the economic sectors energy production, agriculture and navigation. [less ▲]

- Addresses key issues for the allocation of taxing powers in the European Union - Looks at fundamental questions of direct taxation - Covers a broad range of aspects such as limited tax liability, losses or transfer pricing The contributions to this volume try to overcome the traditional approach of the judicature of the European Court of Justice regarding the application of the fundamental freedoms in direct taxation that is largely built on a non-discrimination test. In this volume, outstanding authors cover various aspects of the national and international tax order when European law meets domestic taxation. This includes testing traditional pillars of income taxation – ability-to-pay, source and residence, abuse of law, arm’s length standard – with respect to their place in the emerging European tax order as well as substantial matters of co-existence between different tax systems that are not covered by the non-discrimination approach such as mutual recognition, cross-border loss compensation or avoidance of double taxation. The overarching goal is to flesh out the extent to which a substantive “allocation of taxing powers” within the European Union is on its way to a convincing overall framework and to stretch the discussion “beyond discrimination”.
