The Jihlava (Czech pronunciation: [ˈjɪɦlava] ; German: Igel) is a river in the Czech Republic, a right tributary of the Svratka River. It flows through the Vysočina and South Moravian regions. It is 180.8 km (112.3 mi) long, making it the 8th longest river in the Czech Republic.
Etymology
[edit]The first written mention of Jihlava (written as Giglaue) is from 1226, when it was referred to when demarcating the boundaries of the properties of the Želiv monastery.[1] The origin of the name is often interpreted as coming from the German igel (i.e. 'hedgehog'), but a more likely origin is the Celtic word uig, meaning 'stream'.[2]
Characteristic
[edit]
The Jihlava originates in the territory of Jihlávka in the Křemešník Highlands at an elevation of 666 m (2,185 ft) and flows to the Nové Mlýny reservoirs, where it enters the Svratka River in Ivaň at the elevation of 169 m (554 ft). It is 180.8 km (112.3 mi) long, making it the 8th longest river in the Czech Republic. Its drainage basin has an area of 2,996.5 km2 (1,157.0 sq mi).[3]
