The Sulm (Austrian German: [sʊlm]) is a river in Southern Styria, Austria. It is 29.3 km (18.2 mi) long (66.0 km (41.0 mi) including its longer source river Schwarze Sulm).[1] Its drainage basin is 1,121 km2 (433 sq mi).[2] Its two source rivers Schwarze and Weiße Sulm both originate at the eastern slopes of the Koralpe (a north-south running mountain range in the Southeastern Alps which separates Styria from Carinthia). It flows eastwards towards the Mur through the districts of Deutschlandsberg and Leibnitz. The Sulm valley runs from the Western Styrian hill ranges to the Eastern Styrian hills and lowlands.
