Between 2013 and 2018, striking hydrological and morphological changes were observed in the Tidal Elbe, in particular an unusually strong increase in tidal range, turbidity and sedimentation rates. The latter led to increased maintenance dredging, which, however, represents a major economic and ecological burden. Reasons for the described changes are seen in morphological changes in the mouth of the estuary, persistently low headwater discharges and insufficiently adapted sediment management (Weilbeer et al. 2021). The numerical models currently used cannot adequately represent these developments. In particular, the complex behaviour of cohesive sediments in the heavily anthropogenically influenced river sections such as the port of Hamburg poses a major challenge.
The joint project ELMOD is conducted to improve the predictive capability of numerical models and to improve the understanding of estuarine sediment transport in general. For this purpose, the changes observed in the Tidal Elbe in the period 2013-2018 are analysed by means of hindcast studies and the model approaches used are extended on the basis of natural measurements and laboratory investigations. The partners involved are the Federal Waterways Engineering and Research Institute (BAW, model application), the University of the Bundeswehr Munich (UniBW, development of model approaches) and the Hamburg University of Technology (TUHH, field measurements and laboratory investigations).
