Körös in the context of "Tiszántúl"

Crișana (Romanian: Crișana, Hungarian: Körösvidék, German: Kreischgebiet) is a geographical and historical region of Romania named after the Criș (Körös) River and its three tributaries: the Crișul Alb, Crișul Negru, and Crișul Repede. In Romania, the term is sometimes extended to include areas beyond the border, in Hungary; in this interpretation, the region is bounded to the east by the Apuseni Mountains, to the south by the Mureș River, to the north by the Someș River, and to the west by the Tisza River, the Romanian-Hungarian border cutting it in two. However, in Hungary, the area between the Tisza River and the Romanian border is usually known as Tiszántúl.

The Danube–Criș–Mureș–Tisa Euroregion (DMKT; Romanian: Dunăre–Criș–Mureș–Tisa; Hungarian: Duna–Körös–Maros–Tisza; Serbian: Dunav–Kriš–Moriš–Tisa or Дунав–Криш–Мориш–Тиса) is a euroregion located in Hungary, Romania, and Serbia. It is named after four rivers: Danube, Criș, Mureș, and Tisa.

The Crișul Alb (Romanian), (Hungarian: Fehér-Körös) is a river in western Romania, in the historical region of Transylvania, and in south-eastern Hungary (Békés County).

Its source is in the southern Apuseni Mountains (Romanian: Munții Apuseni) of Romania. It flows through the towns of Brad, Ineu, Chișineu-Criș in Romania, and Gyula in Hungary. Crossing the border of Hungary, the river, now called Fehér-Körös, joins the Fekete-Körös (Crișul Negru) a few kilometres north from Gyula to form the river Körös (Criș), which ultimately flows into the Danube. In Romania, its length is 234 km (145 mi), and its basin size is 4,240 km (1,640 sq mi).

The Crișul Negru (Black Criș) (Romanian), (Hungarian: Fekete-Körös) is a river in western Romania (Transylvania) and south-eastern Hungary (Békés County). The river has its source in the western Apuseni Mountains of Romania. Flowing through the Romanian towns of Ștei and Beiuș and crossing the border of Hungary, the river, now called Fekete-Körös, joins the Fehér-Körös a few kilometres north from Gyula to form the Körös river. In Romania, its length is 164 km (102 mi) and its basin size is 3,820 km (1,470 sq mi). Part of the water from the river Crișul Repede is diverted towards the Crișul Negru by the Criș Collector Canal.

The Crișul Repede (Romanian Crișul Repede ("the rapid Criș"); Hungarian Sebes-Körös) is a river in Bihor County, Crișana, Romania and in southeastern Hungary (Körösvidék). Together with the rivers Crișul Alb ("the white Criș") and Crișul Negru ("the black Criș"), it makes up the Three Criș rivers ("Cele Trei Crișuri"). These are considered the main rivers in the Crișana region of Romania. Historically, when Crișana was recognised as an official region (today, Romania is divided into 40 counties), the Criș rivers were the most important in the region. The basin size of the Crișul Repede is 9,119 km (3,521 sq mi). Its length in Romania is 171 km (106 mi).

The Crișul Repede runs through the city of Oradea, the capital of Bihor County. It flows into the Körös (Criș) near Gyomaendrőd, in Hungary. Part of the water from the Crișul Repede is diverted towards the Crișul Negru by the Criș Collector Canal.
