[en] The AMICE project covers the whole river basin of river Meuse, which extends over parts of France, Belgium, The Netherlands, Germany as well as a small portion of Luxembourg. The goal of the project consists in the development of a basin-wide coordinated strategy to cope with hydrological impacts of climate change, including floods and low flows. As this strategy is intended to be truly integrated at the scale of the international basin of river Meuse, the modelling tools used (e.g., hydraulic modelling, impact assessment, risk management) are also required to be consistent throughout the basin. However, so far, there are as many models and data sets as regions. Each region has developed its own climate scenarios, rainfall-runoff models and hydrological time series as well as its own procedures for hydraulic modelling and risk modelling. This calls definitely for a transnational harmonization effort, as presented here.
