Watershed point

This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.

The watershed point is the point at which one watershed meets another. At the watershed point, the catchment areas for the runoff of rainwater from several (usually three) neighboring river systems border one another.

Naturally, watershed points are generally mountains or corresponding smaller elevations (all around sloping terrain, meeting point of three ridges or ridges).

Main watershed point

Watershed point at the Lunghin Pass near Maloja in the Engadin in Switzerland

Where the main watersheds meet, one speaks of main watershed points (triple points), from there the waters flow into three seas or oceans:

• One of these main watershed points in Central Europe is at the Lunghin Pass near Maloja in the Engadin ( Switzerland ), from which the water flows into the North Sea , the Adriatic Sea and the Black Sea .
• At Glatzer Schneeberg ( Poland / Czech Republic ) is the point from which the water flows into the Black Sea , the Baltic Sea and the North Sea .
• For the two main watershed points of Europe as a whole, see European main watershed points .
• The Triple Divide Peak in Glacier National Park (United States) , the triple point of North America.
• On the border between South Sudan and the Central African Republic is one of the main watershed points in Africa (about 9 ° 8 ′ 23.3 ″  N , 23 ° 28 ′ 5.9 ″  E ). The catchment areas of the Ubangi ( Congo → Atlantic ), the Shari ( Lake Chad ) and the Nile ( Mediterranean ) meet here .

Minor watershed points

On Seehügel in Fichtelgebirge , the watershed between meet Rhine , Elbe and Danube

Where the major watersheds meet minor watersheds, there are minor watersheds, e.g. B .:

• In the central Swiss Alps in the Gotthard massif, the triangle of the cantons of Ticino , Valais and Uri on the main Alpine ridge between Witenwasserenstock , Pizzo Rotondo and Pizzo Lucendro near Bedretto and Realp ( North Sea - Adriatic - western Mediterranean ).
• From the Dreiflussstein near Detmold the water flows into the Ems, Weser and Rhine.
• The catchment areas of the Elbe, Weser and Main (Rhine) meet at the Dreistromstein in the Thuringian Forest.
• The areas of the Danube , Rhine and Neckar meet on the Brogen near St. Georgen in the Black Forest .
