MotivationRegional climate change may lead to modified hydrometeorological regimes which in turn affect river discharge; depending on the vulnerability and sensitivity of the affected natural or managed systems this has variable impacts (on ecology, economy, infrastructure, transport, energy production, water management, etc.). RheinBlick2050 deals solely with impacts, i.e. physical system changes, not with adaptation or mitigation. One of the RheinBlick2050 project's characteristics is that it provides a joint, concerted, trans-boundary view on discharge changes, with institutions participating in the project consortium from nearly all riparian countries of the Rhine basin. Those various institutions and projects provided expertise, data, methods, software tools and numerical model simulations to a common research framework. [1]Data, Methods and Experiment DesignThe experiment design follows a typical hydrological climate change impact study: In a data-synthesis, multi-model ensemble approach a dedicated greenhouse gas emission scenario (here mainly SRES A1B) is used with various global climate models (GCM) (mainly ECHAM5 and HadCM3), regionalized via a dynamical downscaling using regional climate models (RCM). Based on those readily available datasets, after an extensive model chain evaluation and selection, a correction of systematic biases in the daily air temperature and precipitation outputs of the RCMs is done. These fields are used to finally drive the hydrological models (mainly HBV). The hydrological model simulation results are used to analyze changes (expressed as scenario bandwidths and tendencies) in average discharge, low-flow and high-flow diagnostics for selected gauging stations along the Rhine and its major tributaries (Basel, Maxau, Worms, Kaub, Cologne, Lobith, Raunheim and Trier).[1] Project consortium
