This paper examines almost unknown fortifications built to defend strategically important Bratislava´s bridgehead in Petržalka. Interpretation of the 18th – 19th historical maps combined with literary data allows to recognise 3 stages in development of redoubts and earthen embankments, which were most likely first constructed in 1682-3. Remnants of originally eight modest-size redoubts, linked with 2 km long embankment, were during the Napoleonic war (1809) rebuilt by Austrian military into 6 larger, polygonal-shaped earthen outposts. Eventually, during the revolution in 1848 two of them near the Vienna highway were repeteadly strengthened by Hungarian Honvéd Army. Their remnants survived until today.

Endangerment of the village Čunovo (Slovakia) by lateral erosion of the Danube River in the 18th Century.

Pišút, P., 2008. Endangerment of the village Čunovo (Slovakia) by lateral erosion of the Danube River in the 18th Century. Moravian Geographical Reports, 16 (4): 33-44. 9 Figs., 39 refs., 18 historical map references.

Analysis of old maps enabled reconstruction of extremely dynamic channel changes of the Danube River along the part of its Slovak reach at the end of the 18th century. Prior to 1790, rapid development of a new Danube meander led to partial destruction of the small village Čunovo near Bratislava. Stone groynes were constructed to protect the undercut banks and to divert the flow into the new channel. Retreat of eroded banks at Čunovo over the periods 1783-1790 and 1790-1794 reached up to 432 and 229 m, respectively. Corresponding maximum rates of lateral erosion 57-72 m per year and/or 31-76 m during a single event are comparatively high in Central European conditions. Initiation and rapid development of the new meander were related to 1) increased river activity during the last onset of the Little Ice Age period, 2) serious channel changes after 1760 on the immediately upstream reach from Bratislava to Rusovce, 3) siltation of the Lesser Danube, but also to 4) local predisposition of the floodplain topography.

Historical Danube island A l b e r w e r d (werd = older German term for river island) is first evidenced by written sources among several mediaeval islands of Bratislava in 1481 – 1525 (as Alberwer(d)t, Alberswerdt) and later in 1567 – 1578. Additional similar Alberwertel (wertel „little island“) is depicted on a 1698 – 1702 maps (Fig. 1). The island developed from the original gravel bar in the contemporary Danube mainchannel sometime in the late sixteenth- or early seventeenth century (Fig. 2). By colonisation and rapid growth of tree vegetation (Salix sp., Populus sp.) it gradually evolved into 1.7 km long Island of St. Nicolaus (Fig. 3). Alber(n) is German term for a Poplar tree (Populus L.). The local Germans of Pressburg (Bratislava) narrowed its meaning to the Black Poplar (Populus nigra L.). Modern Slovak equivalent for a toponym Alberwerd is „(Black) Poplar Island“. Several hydro- and toponyms were derived from Poplar trees or stands, e. g. the name of the village Albern (today part of Simmering, Vienna city district) or former island Alber(n)haufen (1880 - 1991) near Regensbrunn, at the Austrian stretch of the Danube floodplain upstream from Bratislava.
There was another island with an interesting name close to Alberwertel. Whereas in 1698-1702 (Fig. 1) it was still an unnamed island in possession of Devín (Töbner Au), during 18th century (Fig. 3, 6) it became larger and known as Ru(d)ten-Leber island (Fig. 6). The name consists of German words Rutte(n) and Leber „liver“. Die Rutte (or der Rutten) is the Upper German name for the fish Burbot (Freshwater Codfish, Eelpout, Lota lota, Fig. 5). Burbot is the only European freshwater representative of the Codfish family, common in the Danube. The liver of Burbot have long been a culinary delicacy. The Rudten Leber island was „The Burbot´s Liver“! This bizarre name must have been given to the island by fishermen. Most probably, there was a near resemblance between planform of initial island, clearly seen from adjacent hillslopes (= mid-channel vegetated bar with two accreting lateral gravel bars) and specific three-lobed shape of burbot´s liver. From fishermen´s slang also come names of other local disappeared islands (Gressling; Wolfssdrüssel / Fischdrüssel; Fűszort) and channels (Karpfenwasser).
The 18th Century Rudten Leber island eventually developed into the current Sihoť island, which plays an important role in supplying of drinking water to Bratislava.

Abstract:
Analysis of historical maps from 1770s-1860s within the ArcView GIS environment indicates, that past course of lower Smrečianka river (= right-side tributary of the Váh river in Liptovská kotlina Basin, N Slovakia) in its response zone significantly differed from the present one. The river was not only flowing parallel to the Váh towards west, but also exhibited a meandering planform then with sinuosity index of 1.56. The current low-sinuosity lower reach of Smrečianka (river km 0-1.9) resulted from an avulsion some time in 1820s.

Z najstaršej prírodnej histórie Mostnej nivy a Auparku

Pišút, P., 2004. From earlier natural history of the Bridge Island and Aupark. Acta Musei Civitatis Bratislavensis, 16, 2004, s. 47-74. In Slovak, English summary, 12 Figs., 1 Tab., 85 references.

The Sad J. Kráľa (Park of J. Kráľ), also known as Aupark, is a green oasis in the very heart of Bratislava. This paper examines the earliest history of this former floodplain, as it is documented by numerous historical maps, written sources and botanical evidence. Demolition of old Petržalka and successive extensive development of this city suburb meant decline for the territory, once favourite recreation place. But we watch in dismay that even now it is increasingly in conflict with plans of modern developers. Some unknown facts from its natural history are presented here, which emphasize its unique geomorphological, biological, historical and cultural values (see also a table, 12 reconstruction maps and ilustrative figures).
After some of the major floods around 1712, a new mid-channel gravel bar appeared in 500 m wide Danube mainchannel between Bratislava (then Pressburg) and the village of Petržalka (Engerau). Soon it developed into a more stable island by vertical accretion and vegetation-growth. Its position made crossing the river easier and safer. Before long, two bridges led to the island, hence its German name Brücken Au, Bruck Auel (= Bridge Island, B. islet). The traffic from
Bratislava across the mainchannel was ensured by a „flying bridge“ (= ferry), whereas fixed bridge led from the island to Petržalka across shallower channel, later known as Höllwasser („Hell´s Water“) or Hellwasser („Clear, light water“). After its destruction by the ice flood in 1740, the wooden pile bridge was re-built into the 270 m long impressive structure. Bank revetment and several groynes were constructed to protect banks and the upstream end of the Bridge Island against floods. Original position of its southern bank where it was in 1751 still indicates a shallow terrain depression in the center of park.
After the construction of the right-side embankment with highway to Vienna in 1770s, Hellwasser channel was cut off and silted up quickly. Eventually, also the 200 m wide Croatian channel (Karlburger Arm) was dammed in 1776-1777. During this period of serio
us human interventions Brücken Au ceased to exist as an island. The original name fell into oblivion and the territory was colloquially referred to as Au, in der Au (= on the floodplain). In 1776, original floodplain forest was adapted into one of the first public parks in Central Europe, which became known as Aupark.
Botanical data presented in this study are mainly based on the work Flora Posoniensis (1791), written by Stephan Lumnitzer. List of 52 species of lower and higher plants reported from the Bridge Island comprises several plants, nowadays completely missing from here, vulnerable or critically endangered. We may also learn quite a lot about the character of local habitats in 1780s, which were either substantially altered or do not exist here any longer. The core of the island represented mature floodplain forest with dominant willows and Black Poplar (Populus nigra). Large areas of sand bars and banks were covered by incipient stages of floodplain forest and by shrub willows, with Purple Willow (Salix purpurea), Osier (S. viminalis), locally with German tamarisc (Myricaria germanica). Dry, elevated, sandy treeless banks were covered by heliophilous herbs. Among local trees, several had already been planted in the late 18th Century, such as the unique Yew (Taxus baccata) and some of sycamores (Platanus occidentalis).
Disastrous ice flood in January 1809 heavily damaged both public park and Vienna embankment. I
t also reactivated the Croatian channel, which became reconnected with the Danube after 31 years of siltation. To May of the same year dates back an earthen embankment, encircling the core of Bridge Island in total lenght of 1 447 m. It was built by Austrian corpses to protect strategical approach to Bratislava against progreding French military. In 1825 repair works at the embankment finally began and at the same time connection with the town was established via permanent bridge of boats. This aided further development of the right riverside (= establishment of Aucafé, Arena theatre etc.). In 1830s, damaged floodplain park was rebuilt into its today´s shape of an English park, which provides light, open views of the entire area.
The Bridge Island played an extraordinary role in life and development of modern Bratislava. This study shows that Aupark is not only public arboretum with renewed or re-built historical buildings, but it also represents a precious fragment of the past landscape with well-preserved natural floodplain landforms (= central terrain depression) and artificial landforms (Napoleonic embankment). This values must not be endangered by any of future decisions which might affect this area.

This paper summarizes preliminary results of the study focused on geological characteristics, dating and palaeoecological analysis of sedimentary infill of the former Dudváh River palaeomeander. Study area is located in central part of the Žitný ostrov Island, SW Slovakia, near the village Štúrová. Pollen analysis has been carried on a 100 cm thick sediment profile from paleomeander Štúrová. Analyses of 22 samples characterise the development of the water and terrestrial biotope and the surrounding landscape the last ca 2000 – 2500 years. Pollen transported from longer distances was significant due to the openness of the landscape, coming from northern part of Slovakia mountains. A high degree of afforestation (Abies, Fagus, Picea, woods of alluvial forests) was characteristic for the Younger Subatlantic (X). During Subatlantic period, pollen of synanthropic plants appears. Phases of the aquatic and wetland biotope development were defined on the first (DV-SK1) and second (DV-SK2) zones on the basis of coccal green algae and aquatic and wetland plant ecosystems (Myriophyllum, Trapa natans, Potamogeton). The palynological research was supported by the grants (research program) MZP000257801 (Czech Republic) and VEGA 2/5016/25 and 2/5014/25 (Slovakia).

Humér – zaniknutá stredoveká rieka

Pišút, P., 2007. Humér - zaniknutá stredoveká rieka (Humér - disappeared medieval river).

Download pdf (Stiahnuť článok)

Before planform simplification, several channels were part of anabranching Danube River on the stretch between Bratislava and Komárno. This paper examines a disappeared medieval channel, reportedly over 30 km long, called Humér (in Hungarian: homorú „hollow, curved“, ér „river channel“). In medieval charters it is evidenced from several places, including the villages of Podunajské Biskupice, 16 km away Lehnice (1313 – 1325), Veľké Blahovo / Vydrany (fluvium Humurus, 1298) and the village of Ohrady (marsh Humoro, 1327). Reconstruction of former palaeochannel is based on historical, toponymical and geomorphological evidence (medieval charters data, 18th-19th century and modern topographical maps, field survey). It was found that at least two different channels of the same name existed at the area in question in the past. First and the most important Humér was a side channel of Malý Dunaj flowing from Podunajské Biskupice across Most n. Ostrove, Tomášov to Janíky. This meandering channel (= sinuosity degree 2.19) was only 20-30 m wide but at least 27 km long and it powered several water mills. It was abandoned some time after 1338. Another Humér was flowing via present-day Miloslavov across Mierovo towards the villages of Sása / Lehnice. Most probably, this branch was inactive as early as 1493 and had no connection with additional records of Humér from distant territories of Veľké Blahovo, Vydrany, Ohrady and Nekyje. Rather, they indicate that toponym homorú could be quite common name of minor meandering streams on the territory of historical Hungary.
