Abstract

modelling approach to study climate change impact and adaptation strategies on German inland waterways is presented. In the German federal research program “Network of Experts” a modelling chain that consists of an ensemble of global and regional climate and hydrological models is used to generate hydrological data for a range of climate scenarios. This data serves as input in a novel approach to interlink river engineering related models. As shown for the case study Lower Rhine in Germany, nested one-dimensional, long-term morphodynamic numerical modelling on a large spatial and temporal scale and two-dimensional hydrodynamic-numerical modelling on a more detailed level will be carried out. The River Navigation Assessment Tool (RiNA) connects and weighs model outputs and limitless further information for conducting an integrated waterway assessment. It allows an efficient use of modelling resources and could serve as a decision-making tool for the German Federal Waterways and Shipping Administration to cope with the impacts of climate change.
