Tisza

The Tisza, also known as the Tysa or Tisa, is a major river in Central and Eastern Europe. It was once known as "the most Hungarian river" because it flowed entirely within the borders of the Kingdom of Hungary. It now spans several national borders.

The Tisza River begins near Rakhiv, Ukraine, at the confluence of the White Tisa and the Black Tisa. The Tisza flows west from there, roughly following Ukraine's borders with Romania and Hungary, then briefly following the border between Slovakia and Hungary, later into Hungary, and finally into Serbia. Tiszabecs is the point at which it enters Hungary. It runs from north to south through Hungary. It enters Serbia a few kilometers south of the Hungarian city of Szeged. Finally, it joins the Danube near the village of Stari Slankamen in the Serbian province of Vojvodina.

The Tisza has a length of 966 kilometers and drains an area of approximately 156,087 km2 (60,266 sq mi) (600 mi). Its average annual discharge ranges from 792 m3/s (28,000 cu ft/s) to 1,050 m3/s (37,000 cu ft/s) seasonally. It accounts for approximately 13% of total Danube runoff.

Attila the Hun is said to have been buried beneath a section of the Tisza River that had been diverted.

The Tisza is home to a diverse range of wildlife. Tiszafüred's bird reserve is home to over 200 different bird species. The flood plains along the river are home to a diverse array of plant and animal life. The yearly "flowering" of the Tisza, in particular, is regarded as a local natural wonder. The blooming attracts a large number of mayflies, which is a well-known sight.

Colonies of magnificent bryozoans were discovered in the river in September 2020.
