Abstract The main objective of the Effects of Climate Change On the Inland waterway Networks (ECCONET) EU FP7 project was to assess the effect of climate change on the inland waterway transport network with special emphasis on the Rhine and Upper Danube catchments. The assessment was based on consolidation and analysis of earlier and existing research work as well as application of existing climate change and hydrological modelling tools. A key premise at the planning stage of the project had been that all impact studies conducted within ECCONET should be comparable with each other. This can be guaranteed by the common meteorological and hydrological basis. The climate model simulations, which are the most physics- and process-oriented tools for projecting the future climate evolution, include several uncertainties. In addition, uncertainties exist in the hydrological model simulations. In ECCONET, an effort was made to quantify the uncertainty range by using representative projections that represent both the lower and upper signals of hydrological low-ow parameters for 20212050 over the Rhine catchment. Their evaluation indicated that the nally chosen two regional climate model simulations could be applied also for the Upper Danube catchments as representative projections. The raw climate model outputs have been corrected to the observation data set through application of the linear scaling and the delta-change method. The rst impact studies carried out after validation of the hydrological models resulted in discharge scenarios used as input to the economic models in ECCONET.

1 Introduction
The adaptation to the possible climate change impacts is a great challenge not only nancially, but also from scientic point of view. To prepare an efcient and determined adaptation strategy, a number of comprehensive and quantied impact...
