“…2A). This pattern suggests that terrestrial input to the BS was lower during the Late Glacial than during the Glacial, probably as a result of higher glacial surface runoff owing to reduced vegetation cover and widespread permafrost (20,32). The proxy values peak within the RLs (orange bars in Fig.…”

“…In this scenario, the Caspian spillover would have been mainly caused by high surface runoff within the Volga catchment area due to the combination of reduced vegetation cover, increased seasonality favoring snow accumulation during long winter and rapid spring melting, and widespread permafrost (19,20). This would have resulted in enhanced Volga River runoff, raising the water level of the Caspian Sea and causing its outflow into the BS.…”

“…This would have resulted in enhanced Volga River runoff, raising the water level of the Caspian Sea and causing its outflow into the BS. The FIS contributed to only a minor extent in the Caspian transgression (19)(20)(21). The second hypothesis suggests that deposition of the RLs was directly linked to FIS recession north of the Dniepr drainage basin.…”

Continental ice sheets are a key component of the Earth's climate system, but their internal dynamics need to be further studied. Since the last deglaciation, the northern Eurasian Fennoscandian Ice Sheet (FIS) has been connected to the Black Sea (BS) watershed, making this basin a suitable location to investigate former icesheet dynamics. Here, from a core retrieved in the BS, we combine the use of neodymium isotopes, high-resolution elemental analysis, and biomarkers to trace changes in sediment provenance and river runoff. We reveal cyclic releases of meltwater originating from Lake Disna, a proglacial lake linked to the FIS during Heinrich Stadial 1. Regional interactions within the climate-lake-FIS system, linked to changes in the availability of subglacial water, led to abrupt drainage cycles of the FIS into the BS watershed. This phenomenon raised the BS water level by ∼100 m until the sill of the Bosphorus Strait was reached, flooding the vast northwestern BS shelf and deeply affecting the hydrology and circulation of the BS and, probably, of the Marmara and Aegean Seas.ice dynamics | meltwater routing | European hydrographic network

“…It brings up the question of chronology of the high river runoff epoch in Central and Eastern Europe. In the central part of the East European Plain large meandering palaeochannels (macromeanders) were dated between 18 and 13 ka cal BP (Borisova et al, 2006;Sidorchuk et al, 2009 (Szumanski, 1983(Szumanski, , 1986Vandenberghe et al, 1994;Gębica et al, 2009) and Hungary (Kasse et al, 2010), about 15.5 ka cal BP (12.8 ka 14 C BP) in the Lower Danube region (Howard et al, 2004). In southern Poland some rivers did not change their pattern from braiding to large meanders during the Late Glacial and kept braiding to the beginning of the Holocene (Starkel et al, 1996;Gębica, 2011), other rivers transformed from meandering back to braiding in the Younger Dryas (Starkel and Gębica, 1995), but in all cases the Late Glacial phase of increased fluvial had declined almost exactly at the Younger Dryas / Holocene transition (Gębica, 2013).…”

Absolute chronology of fluvial events in the Upper Dnieper River system and its palaeogeographic implications

et al. 2014

A set of 121 radiocarbon and OSL dates has been compiled from the Upper Dnieper River and tributary valleys, Western European Russia. Each date was attributed according to geomorphic/sedimentological events and classes of fluvial activity. Summed probability density functions for each class were used to establish phases of increasing and reducing fluvial activity. The oldest detected reduction of fluvial activity was probably due to glacial damming at LGM. Within the Holocene three palaeohydrological epochs of millennial-scale were found: (1) high activity at 12,000-8,000 cal BP marked by large river palaeochannels; (2) low activity at 8,000-3,000 cal BP marked by formation of zonal-type soils on -floodplains; short episodes of high floods occurred between 6,500-4,400 cal BP; (3) contrasting hydrological oscillations since 3,000 cal BP with periods of high floods between 3,000-2,300 (2,000) and 900-100 cal BP separated by long interval of low floods 2,300 (2,000)-900 cal BP when floodplains were not inundated -zonal-type soils were developing and permanent settlements existed on floodplains. In the last millennium, four centennialscale intervals were found: high flooding intervals are mid-11-mid-15 th century and mid-17-mid-20 th century. Intervals of flood activity similar to the present-day were: mid-15-mid-17 th century and since mid-19 th century till present. In the context of palaeohydrological changes, discussed are selected palaeogeographic issues such as: position of the glacial boundary at LGM, role of changing amounts of river runoff in the Black Sea level changes, floodplain occupation by Early Medieval population.

Val ley-scale ero sion and change of river style from braided to me an der ing occurred co evally with the de cay of an ice sheet (deglaciation) and the main phase of me an der ing river sed i men ta tion is at tributed to the lat est Elsterian and early Holsteinian.
