The Corhana (Romanian; Moldavian; Moldovan: Corhana, Hungarian: Korhány) is a river in western Romania and eastern Hungary, a tributary of the Crișul Repede. Its source is 2 km south of the village Șauaieu. It flows in western direction towards Cefa, where much of its flow is diverted by the Criș Collector Canal towards the Crișul Negru near Tămașda.[1] Part of its flow continues west and crosses the Hungarian border between Marțihaz and Geszt.[2] The river is diverted into the canals of the drainage system of the area. The meanders of the Korhány near Geszt are a Natura 2000 site.[3]
