Long-term simulation of sediment transport in the Upper Rhine

Description: Das Projekt "Long-term simulation of sediment transport in the Upper Rhine" wird vom Umweltbundesamt gefördert und von Technische Universität Berlin, Institut für Bauingenieurwesen, Fachgebiet Wasserwirtschaft und Hydrosystemmodellierung durchgeführt. This research is a part of the project 'Sedimentmanagement of the Upper Rhine' and carried out in cooperation with BfG. The sediment management in the Upper Rhine River can be affected in the long-term by various natural or anthropogenic activities, e.g. the climate change and land use changes, restoration and engineering measures. To investigate such impacts, a long-term simulation of such scenarios is necessary. In this research, the long-term dynamics of the fine sediment budget in the Upper Rhine will be determined (i.e. how long does it take to refresh the top layer of the deposition?). Furthermore, morphodynamic processes in the Iffezheim reservoir with non-uniform bed composition will also be investigated using SSIIM 3D modeling system. High-resolution numerical models combined with other suitable methods will be chosen for the scenario analyse. The results will serve as the basis for a much coarser sediment budget model of the Upper Rhine. The research will include: - Coarsening of grid - Classification of upstream boundary condition - Time-series analysis - Artificial neural network.
