In this paper we present results of the plant macroremains analysis from organic sediments of the Gbelce depression (lower Hron Hill land, SW Slovakia). The coring site (Nová Vieska 2.) is situated on the floodplain of the Paríž brook. The 283 cm deep profile represents sedimentary record, covering the whole period from the Late Glacial (9 674 cal BC) to the Modern Age. Based on plant macrofossils and 8 radiocarbon (AMS) data, hydroseral succession can be subdivided into the 6 local analytical zones, reflecting changing composition of local marsh vegetation over time. Infilling of the Gbelce depression markedly accelerated from the Younger Atlantic – Early Subboreal period onward, due to forest clearance and input of eroded fine particles from adjacent slopes. Plant macroremains also reveal a pronounced change in water regime during medieval period which helps to explain historic occurence of local „floating islands“ (reported from 18th Century). Plant macrofossils also enable to track an early presence of humans in the adjoining landscape which dates back into the Eneolithic period (it is mainly indicated by numerous achenes of Cyperus fuscus and Ranunculus sceleratus). The paper brings new data on the development of the Nature Reserve Parížske močiare.

During study of 18th century historical documents we found some information about two former flood marks from the Danube flood of 1775 in Bratislava. In this article we explain results of our investigation of specific sites, where these flood marks were originally located. We bring knowledge about the course of this ice flood on the Danube River in Bratislava based upon the study of historical records (mainly newspaper Preßburger Zeitung).

This so called „All Saints Flood“ most badly hit the Austrian reach of the Upper Danube and the Slovak section of the Middle Danube, with the severest material damage to the area of current large Bratislava (suburbs of Petržalka and Rusovce). With estimated peak flow of 11 800 m3.s-1 it had a character of 200-500-year flood in Bratislava. This paper is aimed to reconstruct the casues, course and effects of the flood, mainly based on analysis of contemporary reports published in the local German newspaper Preßburger Zeitung, supplemented by the depictions of 1781-1790 manuscript maps. This flood was exceptional by its occurence in the autumn period and also had a pronounced geomorphic effects. Fortunately, the high flow only took a minimum toll of lives in Slovakia and its destructive impacts on residential buildings, boat mills and vessels were not that devastating as in the case of other large floods, mainly those caused by jammed ice. Nevertheless, it was one of the two most destructive events (1787, 1809) that badly damaged the right-bank artificial levee of Petržalka, an important local protective structure to prevent flooding and facilitate transportation with Vienna.

Since 1965, the Danube River in Bratislava, Slovakia has not been completely frozen. However, in the past the ice on Slovak rivers was a common phenomenon. But river ice also signalled the imminent threat of dangerous and hard-to-predict ice floods. Floods due to ice barriers often accompanying ice break-up were common in our latitudes during periods of wetter and cooler climate (e. g. Little Ice Age). The ice was responsible for some of the most disastrous floodings in European rivers. Despite the current extent of river regulations and ongoing global warming, the threat of ice-jam floods is far from being over. In this respect, study of past winter type floodings can provide us with precious knowledge of the origin, course and possible consequences of these natural hazards. In this paper we report of so far little known ice-breakup flood of 1826, that occurred in the Danube River, Slovakia. After six weeks of frozen Danube the relatively cold winter eventually ended with the ice disintegration and movement on February 27, 1826. Clogging of the Danube channel with ice resulted into succesive ice jam flooding in the Bratislava reach and in some parts of Žitný ostrov Island. Our findings are based on reports from local newspaper (Preßburger Zeitung) and cartographic evidence.
