“…Following Rosgen [22] classification of river valleys, the valley is of a lacustrine type. Rakutowskie Lake has a melt genesis which is typical of young glacial areas [21,[23][24][25]. The Płock Basin area is composed of quaternary sediments whose thickness reaches 35-40 m, represented primarily by rather lithologically homogenous sand-gravelly fluvioglacial series, locally separated by a series of silt-clay sediments [26,27].…”

In this work we present the complicated situation of a faunistically and floristically valuable ecosystem of the Rakutowskie Lake wetlands complex, which is part of the Special Protection Area for Birds of “Błota Rakutowskie” (PLB40001) and “Błota Kłócieńskie” Habitats Directive Sites (PLH040031) included in the Natura 2000 network. Numerous ornithological observations have drawn our attention to the problem of rapidly progressing overgrowth of the lake and significant fluctuations in its water surface area. These fluctuations, especially in the spring period, significantly limit safe reproduction possibilities of very rare species of water–marsh birds. A multidirectional and comprehensive spectrum of research works allowed us to determine the genesis of the ecosystem and show that the shallow lake is undergoing the final stage in its evolution. The economic aspect of human activity (changes in land use and land development works) has contributed to serious degradation of the ecosystem. Climate changes observed in recent years (increased air temperature and, consequently, higher evaporation) additionally deepen and accelerate this process. The research made it possible to determine how the ecosystem functions today, but it is also an attempt to determine our predictions about its future.

ELISABETH DIETZE, MICHAŁ SŁOWIŃSKI, IZABELA ZAWISKA, GEORG VEH AND ACHIM BRAUER 2 3Dietze, E., Słowiński, M., Zawiska, I., Veh, G., Brauer, A.: Multiple drivers of Holocene lake 4 level changes at a lowland lake in northeastern GermanyMany German lakes experienced significant water level declines in the last decades that are 7 not fully understood due to the short observation period. At a typical northeastern German 8 groundwater-fed lake with complex basin morphology, an acoustic sub-bottom profile was 9 analysed together with a transect of five sediment cores, which were correlated using multiple 10 proxies (sediment facies, µ-XRF, macrofossils, subfossil Cladocera). Shifts in the boundary 11 between sand and mud deposition were controlled by lake level changes, and hence, allowed traced continuously using the Calcium-record. During high lake levels, massive organic muds 15 were deposited in the deepest lake basin, whereas lower lake levels isolated the sub-basins 16 and allowed carbonate deposition. 17During the beginning of the Holocene (>9700 cal. a BP), lake levels were high likely due to final 18 melting of permafrost and dead-ice remains. The establishment of water use intensive Pinus 19 forests caused generally low (3-4 m below modern) but fluctuating lake levels (9700-6400 cal. 20 a BP). Afterwards, the lake showed an increasing trend and reached a short-term high-stand 21 ~5000 cal. a BP (4 m above modern). At the transition towards a cooler and wetter late 22 Holocene, forests dominated by Quercus and Fagus and initial human impact likely 23 contributed more positively to groundwater recharge. Lake levels remained high between 24 3800 and 800 cal. a BP, but the lake system was not sensitive enough to record short-term 25 fluctuations during this period. Lake level changes were recorded again, when humans 26 profoundly affected the drainage system, land cover and lake trophy. Hence changes, e.g. macrofossils and the position of the sediment limit, i.e., the upper limit for the 68 predominant deposition of organic-rich mud related to sediment focusing (Digerfeldt 1986; 69 Dearing 1997). The "Digerfeldt approach" has provided reliable lake level reconstructions 70 across the globe (e.g. Punning et al. 2004; Shuman et al. 2010;Haig et al. 2013), but so far has 71 been restricted to shallow lakes <100 ha with simple basin morphologies (e.g. low-angled In the central European lowlands, hydrological reconstructions primarily rely on records from 74 small lakes or peat bogs (Gałka et al. 2013(Gałka et al. , 2014 Słowiński et al. 2015). In northeastern Germany, a high sensitivity of lakes to Holocene hydrological changes has been suggested (e.g. 76Lampe et al. 2009; Kaiser et al. 2012 Kaiser et al. , 2014b Küster et al. 2014); however, well-dated lake 77 level reconstructions remained restricted to certain times. 78Lake Fürstenseer See, a typical groundwater fed lake with complex morphology has 79 already showed pronounced changes in lake level and size during the instrumental period 80 (Germer et ...

“…The geologic setting is in the range of thick deposits related to the North Polish Glaciations (Słowiński et al 2015). Fluvioglacial sands and gravels represent the Hrubieszów interstadial, while the main stadial is represented by glacial till, fluvioglacial sand and gravel or glacilacustrine muds.…”

The paper discusses difficulties of identifying the causes of a landslide. These difficulties are illustrated in the example of a catastrophic landslide on the embankment of the western bank of the Brda River, which affected a bridge abutment of a disused narrow-gauge railway line from Bydgoszcz to Koronowo (Polish Lowlands). The railway was closed in 1992, and after the removal of the track, the bridge served as a pedestrian overpass. The landslide occurred in February 2011. Investigations revealed that the first signs of the landslide were cracks and subsidence that appeared at the embankment crest. Then, an initially slow movement accelerated suddenly, resulting in an over 45 m total displacement of the soil mass. The primary passive cause of the landslide movement resulted from the geology of the mass (loose soils underlain by cohesive soils) and from the steep inclination of the embankment surface. Active causes, however, are often ambiguous. In this case, no significant apparent phenomena which could trigger the movement occurred in the days preceding its initiation. Therefore, a detailed analysis of atmospheric conditions was carried out to identify and explain the causes. It was proved that the fundamental triggering cause of the landslide was a combination of rainfall, snowfall, snow-melting and air temperature. Moreover, an important cause was a faulty construction of a ditch with a sewage pipe on the crest of the embankment.
