Abstract During the flood event in 2021 within Western Europe, many bridges were severely damaged, particularly North Rhine‐Westphalia and Rhineland‐Palatinate Germany. Within this study, a statistical analysis of damages caused to by was carried out. First, locations along rivers Inde, Vicht Ahr mapped. Based on these data, correlations among damage patterns analyzed. Approximately 25 both Inde while over 80 damaged. Notably, located near residential areas suffered more severe than those...
Abstract Background This study explores morphologic changes in the Ahr River, Germany, caused by high-energy flood mid-July 2021. aims to assess flood's significance as a morphological driver using Lateral Mobility Index (LMI), well impact of infrastructure on morphodynamics terms formation mud deposits and stagnant water pools, considering three focus areas about 1 5 km river length. The cover differences valley morphology near natural anthropogenically affected sections. Results LMI is...
The narrow valley parts of the Ahr river are located in a low mountain region on edge Volcanic Eifel. In July 2021, flash flood formed, and energetic water masses with high flow velocities drove significant morphodynamic change sediment displacements along river. riverbed banks experienced erosion, floodplains showed slope erosion by surface runoff. other locations, we observed floodplain sedimentation infill. Large lenses formed floodplains, gravel bank deposits, partly organic content,...
The extreme flood event of July 14/15, 2021 caused massive geomorphological changes along the Ahr river in western Germany. processes include mass movement and bank erosion, channel displacement widening deposition material at floodplains, all which contributed to damage. With aim gaining a more comprehensive understanding factors controlling these processes, spatial patterns on regional scale are analyzed. A differential terrain model (DoD), calculated from digital models (DTM) collected...
In mid-July 2021, heavy rainfall led to severe flash floods in the Eifel-mountain region western Germany. The Ahr River, a tributary Rhine River Rhineland-Palatinate, was most severely affected. Discharges accumulated rapidly narrow valley and formed fast-moving flood wave, leading record-breaking water levels. High hydraulic forces combination with driftwood debris accumulation local back-up, eventually failure of many bridges [1].The is proven be high-energy event that significant...

This paper presents a dataset documenting 71 floating debris accumulations at bridges following an extreme hydrological event that hit Belgium and Germany in July 2021. Data were collected from various sources including public authorities' documents, online databases, post pictures field visits. The covers geometry, flood conditions accumulation. In particular, it systematically details dimensions quantifies components, which contain significant portion of anthropogenic objects, addition to...
In the summer of 2021, devastating river floods occurred in Western Europe as a result extreme rainfall. At numerous bridges, debris accumulations were observed, exacerbating flooding upstream by impeding waterflow and sometimes contributing to bridge failure. Due widespread building damage settlements along rivers, these differed markedly from classic logjams, with substantial amounts man-made objects. A new database clogged bridges Belgium Germany – described separate data descriptor was...
Abstract Background: This study explores morphologic changes in the Ahr River, Germany, caused by high-energy flood mid-July 2021. Infrastructure systems influence river morphology, but causal relationships are challenging to establish. The aims assess flood's significance as a morphological driver using Lateral Mobility Index (LMI), well impact of infrastructure on morphodynamics terms formation mud deposits and stagnant water pools, considering three focus areas about 1 5 km length....
