“…However, there is no data how long the braided planform was active, and what planform replaced it. Tóth et al (2017) show that the middle Danube maintained a meandering course in the Holocene. Paleomeanders have been preserved on two floodplain levels and this points to the river incision about 4700-5000 BP (OSL dating) (Tóth et al, 2017).…”

This study aims to explain the influence of sediments and landforms of postglacial and loess landscapes of Europe on processes forming meandering and anabranching rivers. Based on a literature review, sedimentary architecture, types and grain-size of deposits, and channel planform changes since the Late Pleniglacial were collected for extensive set of European rivers. These data were used to create a conceptual model explaining the evolution of meandering and anabranching rivers in both types of landscape. The present study shows that the inheritance of glacial and fluvioglacial landforms and sediments, and loess formation, influence types of processes forming anabranching and meandering rivers. Point bar accretion formed meandering rivers in postglacial zone whereas oblique accretion dominated in loess areas. Anabranching rivers of postglacial zone evolved through the formation of crevasse channels and meandering anabranches. Anabranching rivers of loess zone formed sustained bifurcations. Postglacial and loess rivers reacted differently to increased deposition and humidity in the Late-Holocene. Meanders of postglacial zone formed channel bars owing to increase in stream power and sediment load. In cases of flow energy decrease, and sustained upstream sediment delivery, they turned into anastomosing rivers. Anabranching rivers in ice-marginal valleys maintained its courses until hydro technical works in the 19th century. Low-energy meandering rivers of loess areas became wetlands owing to deposition of silts. High-energy meandering and anabranching rivers maintained the planforms throughout the Holocene. These findings need to be refined by detailed studies on the evolution of rivers in subarctic zone, and large rivers of Europe.

“…The local base level further decreased ∼5,000 cal. yr BP owing to the incision of the Danube River (Tóth et al., 2017). Despite this event, an increase of aggradation to 1.0–4.0 mm y −1 took place during the last ∼2,000 cal.…”

A sedimentary record of channel planforms preserved in alluvial sediments provides information about past climate changes. This is because dry and humid periods influence the magnitude of discharge, sediment load, channel width and depth, velocity, slope, and roughness (Leopold & Wolman, 1957). These interactions are recorded in fluvial sedimentary architecture. There are seven orders of elements constituting fluvial sedimentary architecture -from the single lamina, through bar surface, bars, nested channel cuts, channel fills and channel belts, to a nested valley (Miall, 1985). The record of channel belts includes information about the type of channel planform including records of past fluvial events that is, channel cutoffs, avulsions, the occurrence of floods, and changes in sedimentation style.

“…The incision of the Danube in the Danubian Plain at ~30 ka (Tóth et al . 2017; Sebe et al . 2019) caused the denudation of the western margin of the alluvial fan, possibly the coarsest material of magnetic susceptibility cycles II and III.…”

High‐resolution stratigraphical architecture of a Quaternary fluvial succession in the Makó Trough and the Danube‐Tisza Interfluve (Pannonian Basin, Hungary) was investigated based on low field magnetic susceptibility (MS) measurements of seven fully cored boreholes, interpreted on the basis of the early postglacial magnetic susceptibility episodes previously described in the Körös and Jászság Basins. To confirm the reliability of the Dévaványa and Vésztő MS records (Körös Basin), the published magnetostratigraphical data were re‐investigated revealing the consequent arrangement of the MS peaks correlated with the Jingbian section and the short‐lived polarity reversals correlated with the Geomagnetic Instability Time Scale. The Quaternary climatic regime in the Körös Basin begins in the late Pliocene at 2.7 Ma. The correlation between the Körös Basin (Dévaványa) and Makó Trough (Mindszent) was confirmed by the multi‐proxy spectral investigation of the Mindszent section, revealing ~100‐ and ~41‐ka cycles in the MS, colour, logged spontaneous potential and resistivity records. Based on MS records of the seven boreholes, the base of the Quaternary can be identified irrespective of the facies, age and climatic phase of the lowermost Quaternary strata. By performing MS and log correlation of 131 boreholes, extended unconformities were detected in the Quaternary profiles in the Danube‐Tisza Interfluve (~1070±10, ~1920±10 and ~2300±10 ka) interpreted as sequence boundaries. Sedimentological and mineralogical data reveal a significant change at ~725–606 ka likely as a response to the ‘mid‐Pleistocene transition’, leading to the multiple branching of the Danube. SEM data revealed that ilmenite is also responsible for the development of the early postglacial magnetic susceptibility episodes. This increases the stratigraphical potential of fluvial successions with catchment area that contain metamorphic rocks. A gradual retreat of permafrost zone determines long‐term temporal trends of the climatically controlled fluvial magnetic susceptibility episodes, causing upward decreasing trends in the time series.
