Abstract: Žitný ostrov, the largest island of the Danube River (SW Slovakia) was formed to its present-day shape in the Neoholocene period. As a result of increased flood and geomorphological Danube river activity dated to 1378-1528 AD, the lower Dudváh River was abandoned and its alluvium became a part of the Žitný ostrov. Study of Dudváh terrestrialised palaeomeander by means of pollen and macrofossil analysis provides new information about the palaeoenvironments of the Danube Plain. Meander under study was cut-off during the Sub-Boreal period when the land was mostly covered by oak-dominated mixed forest with a notable high frequency of Fagus and Abies. At low-lying depressions, Alnus glutinosa have formed typical alder carrs. The largest decline of the mixed forest occurred during the Sub-Atlantic period. Until the mid-19th century the region was strongly influenced by shallow groundwater and periodical floods, as reflected by pollen of aquatics and marsh species. Amongst non-arboreal taxa, pollen of Cyperaceae, Brassicaceae/Cuscuta, Poaceae and Apiaceae prevailed. Local successional changes started with i. stage of abandoned oxbow still with influx of moving water, poor in both macrophytes and molluscs, ii. shallow eutrophic oxbow lake with slowly flowing or stagnant water overgrowing with aquatics (Ranunculus subgen. Batrachium, Potamogeton sp., Ceratophyllum demersum etc.) abound with molluscs, iii. an open marsh dominated by Cyperaceae (mainly Carex riparia) with Atriplex prostrata, supporting diverse molluscan and Ostracod fauna. Present-day habitat is a result of landscape changes, which have been associated with draining, intensified agriculture, ruderalisation and spread of invasive species.

Protiturecké pevnosti na ochranu bratislavského predmostia na historických mapách 17.-19. storočia.

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.
