The Vltava (Czech pronunciation: [ˈvl̩tava] ( ); German: Moldau, IPA: [ˈmɔldaʊ]) is the longest river in the Czech Republic, running north from its source near the German border in Šumava through Český Krumlov, České Budějovice, and Prague, merging with the Elbe at Mělník.

Physical description[edit]

It is 430 kilometres (270 mi) long and drains about 28,090 square kilometres (10,850 sq mi). At its confluence with the Elbe, the Vltava actually has more water than the Elbe and is even much longer, but it joins the Elbe at a right angle to its flow so that it appears to be a tributary. The river is crossed by 18 bridges (including the famous Charles Bridge, shown below) as it runs through Prague. It covers 31 kilometres (19 mi) within the city.[1] The water from the river was used for drinking. For instance, until 1912 the Vinohrady Water Tower pumped the water directly from the river.[2]

Several dams were built on it in the 1950s, the biggest being the Lipno Dam in Šumava. In August 2002, a flood of the Vltava killed several people and caused massive damage and disruption along its length.

The height difference from source to mouth is about 1,016 metres (3,333 ft) and the largest stream at the source is named Černý Potok (Black Brook).

Both the Czech name Vltava and the German name Moldau are believed to originate from the old Germanic words *wilt ahwa[3] ("wild water") (cf. Latin aqua). In Annales Fuldenses (872 AD) it is called Fuldaha; from 1113 AD it is attested as Wultha. In Chronica Boemorum (1125 AD) it is attested for the first time in its bohemised form as Wlitaua.

Use in culture and science[edit]

One of the best-known works of classical music by a Czech composer is Bedřich Smetana's Vltava, which is usually called The Moldau on recordings and in programs. It is from the Romantic era of classical music and is a musical depiction of the river's course through Bohemia (listen).

A minor planet 2123 Vltava discovered in 1973 by Soviet astronomer Nikolai Stepanovich Chernykh is named after the river.[4]

Smetana's symphonic poem also inspired a song of the same name by Bertolt Brecht. An English version of it, by John Willett, features the lyrics Deep down in the Moldau the pebbles are shifting / In Prague three dead emperors moulder away.[5]
