Originating in the Fischbach Alps, the Raab flows primarily over the Middle Danubian Plain (Little Alföld), merging with the Moson Danube. There is high water in spring and flash floods in summer. The mean flow rate is approximately 70 cu m per sec. There are freeze-ups from time to time in January and February. The flow is regulated, and the channel is canalized in the lower course. The river is navigable below Körmend (Hungary). The Raab is used for irrigation. The city of Győr (Hungary) is near the mouth.
