Chamb 昌布河
The Chamb (German:Chamb; Czech:Kouba) is a river in the Czech Republic and in Germany. It is a 51 kilometres (32 mi) right tributary of the Regen River.
The Chamb begins south of the Czech village of Kdyně, and flows some 6 kilometres (3.7 mi) westward, crossing into Germany at an elevation of 407 metres (1,335 ft). From there it flows southwestward through Eschlkam, Furth im Wald, and Arnschwang, joining the Regen east of the city of Cham (whose name is of similar Celtic etymology).
