The Chamb begins south of the Czech village of Kdyně, and for some 6 kilometres (3.7 mi) flows 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).
The discharge of the Chamb is variable. The highest and lowest recorded flow rates are 60.8 m (2,150 cu ft) per second (July 9, 1954) and 0.36 m (13 cu ft) per second (June 9, 1960).
