Impact assessment of river regulations using 1d morphodynamic modeling on the Upper Hungarian Danube

Abstract
The geometry of watercourses shows that they undergo continuous deformation towards a dynamic equilibrium state. Once this is reached, further changes in the bed can be observed, but they are not expected to cause significant deviations from the dynamic equilibrium state. The dynamic equilibrium state will likely change due to significant natural or artificial processes. The main question is what new riverbed geometry or flow conditions (peak water levels) can be expected. In our paper, we investigate the impact of past interventions on the dynamic equilibrium state of the Upper Danube in Hungary. We built a 1D morphodynamic model for the section under study. The model was improved by incorporating the mixed grain composition of the bed and bedload material and considering the backwater effect. The model was parameterised with data from the 19th century, i.e. the natural state. The model allowed us to perform a century-scale study. The model gave accurate results of 13 cm and 3 cm for the incorporation of the interventions and also predicted the backfilling in the studied section. Using the 1D approach, we obtained a model that can study a more extended section, such as a more than 100 km reach. The 1D model can provide a temporal estimate of the impact of each intervention, Such as the installation of wing dam fields and water dams and the elaboration of artificial cutoffs.
