What is "obrh"

Obrh Creek is a losing stream that originates and terminates in the Lož Karst Field in the Municipality of Loška Dolina. It is a watercourse in the Ljubljanica watershed. It is created by the confluence of Little Obrh Creek and Big Obrh Creek ; the latter is fed by two tributaries: Brežiček Creek and Viševek Brežiček Creek . The confluence, at which point it is simply named Obrh, lies west of the village of Pudob. In the northwest, limestone part of the karst field, Obrh Creek starts to drain into many sinkholes, and higher water flows into Golobina Cave. The stream re-emerges at a spring to the northwest on the southeast edge of the Cerknica Karst Field.
