Ybbs River Network (YRN) - a lower-alpine stream network


The Ybbs River stream network is located in lower Austria approximately 120 km from the City of Vienna (14°57'00.8'' E 47°48'22.9''N). It represents a fifth-order lower-alpine stream network draining a a catchment area of 254 km2. The lowest elevation of 531 m (a.s.l) is located at the Ybbs River sampling site. The highest elevation is represented by the 1878 m (a.s.l.) Dürrenstein peak - a well known summit for hikers.

The river network can be subdivided into four main valleys, the Ois valley, the Steinbach valley, the Bodingbach valley and the Seebach valley. The latter also includes the Oberer Seebach (OSB) long-term monitoring site.

Past work within the Ybbs River Stream Network was mainly based on data priviously collected by the Battin group. These include efforts to estimate ecosystem metabolism (lead: Amber Ulseth, now at EPFL), as well as estimating CO2 evasion from this steep terrain (lead Jakob Schelker). These efforts are performed in collaboration with Tom Battin and Gabriel Singer.
