description
The valley extends in South Moravia from southwest to northeast between Znojmo and Brno . It is named after the rivers Thaya ( Dyje ) and Schwarza ( Svratka ); the Thaya flows through the southern part of the depression, its tributary Schwarza through the northeast.
In the north it borders on the Bobravská vrchovina ( Bobrawa Uplands ) and the Drahanská vrchovina ( Drahaner Uplands ), to the northeast it is connected to the Hornomoravský úval ( Upper Moravian Depression ) via the Vyškovská brána ( Wischauer Gate ) . To the east are the Ždánický les ( Steinitzer Forest ) and the Dolnomoravský úval ( Southern March Basin ). The Mikulovská vrchovina ( Nikolsburg cliffs ) rises to the southeast . To the south, the depression continues on Austrian territory in the Laaer Bucht to the Weinviertel hill country . To the northwest lies the Jevišovická pahorkatina ( Jaispitzer hill country ).
The Czech part has an extension of 1452 km², the mean height is 210 m nm. The highest point is the Výhon ( 355 m nm ), the deepest is ( 170 m nm ) on the Nové Mlýny reservoir.
The depression consists of sediments from the Tertiary and Quaternary periods as well as loess in the river terraces and floodplains. It is one of the areas with the lowest rainfall in the country. The valley basin is one of the regions with a warm climate. In the winter months the temperature is only slightly below zero, in summer an average of nineteen to twenty degrees Celsius is reached. The depression was the only nesting area for the great bustard in the Czech Republic. The soils are mainly used for agriculture. Except for alluvial forests along the rivers, the area is almost free of forests. The appearance of the valley is shaped by numerous rivers, including the Thaya, Svratka, Jihlava , Jevišovka .
In the valley basin there are nature reserves such as Hradišťské terasy (with remains of medieval orchards and a vineyard terrace ), Kraví hora , Pustý kopec and Havranické vřesoviště .
