“…It was conducted in the years 2016-2018, and concentrated on the record of extreme processes at four sites located in outcrops of the cliff on the Jeziorsko Reservoir in Siedlątków. It documented sedimentological record of the jökulhlaup which occurred there, in the form of erosional channels filled with bouldery-gravelly sediments, which resembles rapid floods in the marginal zones of Icelandic glaciers (Frydrych and Rdzany 2018). The thickness of the deepest channel reaches the maximum of about 10 metres.…”

“…Sudden water discharges may have been facilitated by fast movement of ice masses with features of a surge, related to the local post-maximal phase of Wartanian ice sheet activation. Palaeohydraulic analysis allowed the glacial water flow velocity to be estimated at about 6 m*s -1 in the largest channel (Frydrych and Rdzany 2018).…”

“…Literature related to Scandinavian glaciations in the Polish lands is short of sufficient synthetic studies on this subject, and it often contains only scattered information on the occurrence of floods, included merely as an addition to other research objectives. Additionally, the experience gained by the authors from research conducted in central Poland (Frydrych and Rdzany 2018) encourages them to perform a review of research conducted in the marginal zones and forelands of the consecutive Pleistocene glaciations in Poland, for which these zones are preserved either in the landscape or only in the geologic record.…”

In international literature, much attention has been paid to sedimentological and geomorphological evidence of extreme floods in the forelands of both contemporary and Pleistocene glaciers and ice sheets. Reports on this subject come from areas and periods of different glaciations. In Poland such events have been documented in more than ten works. This situation prompts us to establish whether or not the occurrence of such extreme events was more frequent and widespread in the area of Poland than it has been believed to date. The article reviews the existing research concerning within the extent of Pleistocene glaciations in Poland, which include the occurrence of high energy glacial outburst floods in the interpretation of sediments or landforms. Its objective is to determine the current state of knowledge and to indicate the direction of further research. The review also includes a study of palaeogeographic conditions of the previously documented jökulhlaup in Siedlątków, on the border of the Łask Heights. The analysis of works and the conducted comparisons lead to the conclusion that the state of knowledge about great glacial floods in the Polish Lowland is not satisfactory. It indicates the need to undertake intense studies on the record of such events and their reconstruction as their morphogenetic role e.g. in the formation of ice-marginal valleys and other elements of glacigenic landscape is underrated.

Zarys treści. W artykule podjęto próbę określenia zmian geomorfologicznych i sedymentologicznych w południowej części Zbiornika Jeziorsko, zaistniałych pomiędzy latami 2009 i 2011, głównie jako skutek powodzi w maju i czerwcu 2010 roku. Zobrazowano dane przestrzenne, m.in.: zasięg procesów depozycyjnych, objętość i rozkład miąższości osadów oraz zmiany kształtu form rzeźby powstałych w górnej części zbiornika i w jego najbliższym sąsiedztwie w zasięgu dna doliny Warty, a także inne, powiązane z nimi zmiany środowiskowe. W tym celu wykorzystano: dane pomiarowe LiDAR (Light Detection and Ranging) z lotniczego skanowania laserowego ALS (Airborne Laser Scanning) pozyskane w latach 2009 i 2011, zdjęcia lotnicze i satelitarne z dotychczasowego okresu istnienia zbiornika oraz przed jego powstaniem (1976-2022) oraz archiwalne dane kartograficzne, geologiczne, hydrologiczne i botaniczne. Stwierdzono, że powódź spowodowała m.in.: częściowe zapełnienie koryt w obrębie delty, podniesienie powierzchni obszarów międzykorytowych, zakłócenie regularności zarysów wcześniej ukształtowanych koryt i form międzykorytowych oraz utworzenie kilkudziesięciu drobnych pagórków o średnicy od kilku do kilkunastu metrów i wysokości do 1 m. Miąższość zdeponowanych osadów na przeważającej części obszaru osiąga 0,5-1,0 m, przy pojawieniu się niewielkich terenów cechujących się ich ubytkiem. Stwierdzono powiązanie zasięgu akumulacji rumowiska w następstwie powodzi ze środkową i północną częścią delty, szczególnie w strefie roślinności wysokiej.
