Etymology
editThere are several theories about the origin of the name. One of the more likely theories says that the name could be derived from the Proto-Slavic verb sadjati (modern Czech sázet, usazovat), meaning 'to sediment', 'to sink to the bottom'. According to another theory, the name has its basis in the Celtic word sathá, which meant 'grove', 'forest', as well as 'swarming', 'flickering'.[1] The attribute "Moravská" (indicating its affiliation both to Moravia and to the Morava River) distinguishes the river from the Sázava River.
Characteristic
edit
The Moravská Sázava originates in the territory of Výprachtice in the Orlické Mountains at the elevation of 794 m (2,605 ft) and flows to Zvole, where it enters the Morava River at an elevation of 277 m (909 ft). It is 53.9 km (33.5 mi) long. Its drainage basin has an area of 510.6 km2 (197.1 sq mi).[2] The average discharge at its mouth is 4.52 m3/s.[3]

Settlements

Bodies of water
edit
There are 169 bodies of water in the basin area. The largest of them is the Nemilka Reservoir with an area of 18.9 ha (47 acres), built on the Nemilka Stream.[2] No reservoirs or fishponds are built directly on the Moravská Sázava. A notable construction is the dry detention basin Žichlínek, which is the largest detention basin in the Czech Republic. It was built on the river in 2008 as flood protection, after the region was severely hit by the 1997 Central European flood. It has an area of 166 ha (410 acres).[5]
Nature
editMoravská Sázava is also the name of a Special Area of Conservation with an area of 353.4 ha (873 acres). It is a floodplain of the river and a forested landscape next to the river, located on the upper course of the river.[6]
