Talk:Ombla

Query

 * The article says "The river rises as a karst spring fed by groundwater replenished by Trebišnjica, which is an influent stream flowing in Popovo Polje,". As the Ombla has such a big flow, is this "groundwater" actually an underground river in a cave? If so, the Ombla is merely the lower end of the Trebišnjica.

 * It's not as simple. There's no underground river in a cave, but a spring in a cave metres from the place where the water clears surface. Trebišnjica sinks in series of ponors and that water reemerges in a considerable number of springs. Ombla is fed by one of those, but the largest one forms Buna (Neretva) and there are many more. The above statement that Ombla "rises as a karst spring fed by groundwater replenished by Trebišnjica, which is an influent stream flowing in Popovo Polje" is quite accurate as Trebišnjica really replenishes an aquifer in Popovo Polje area (depicted on a map in the article) which is in turn source of a number of karst springs and underwater springs (vrulje) in the Adriatic Sea - there is no single line of water flow (i.e. underground river) between Trebišnica's final ponor and Ombla spring. IMO the article accurately says where the water comes from - and yes, that's Trebišnjica - and it also describes how it gets to the place where it's called Ombla.--Tomobe03 (talk) 09:19, 30 September 2012 (UTC)

Exact location of river mouth
Can we consider the weir (30 meters from spring) as the river mouth? About 80 meters from the weir downstream there is a bridge with title "Ombla", and 15 meters from the bridge you can see the point where the water flow from spring mixes with the water flow from the direction of sea. — Preceding unsigned comment added by 217.197.142.62 (talk) 08:46, 5 January 2014 (UTC)
 * The article reflects contents of reliable published sources. Bridge names, on the other hand, may be entirely arbitrary. Find reliable published sources presenting information to the contrary and I'll see to it that both points of view are presented in the article.--Tomobe03 (talk) 11:38, 5 January 2014 (UTC)
