Sediment accumulation and flooding within the focus area. Map A provides the inundation area (light blue), which exceeds the previously mapped extreme flood limits (darker blue). Additionally, all floodmarks are given. Map B provides the modeled sediment accumulation in the same area. The yellow-brownish colors indicate sediment deposition, with darker shades implying more intense sediment deposition. The red line gives the limits of the area included in the sediment deposition model. The blue color indicates a reconstruction of the areas flooded in July 2021. Additionally, all sampling points are given. Only the 6 sediment samples collected within the model area, as indicated by the red line, were used for the model
