Antecedent drainage stream

Antezendenz is a term used in geology.

If a flow forced by sustained elevation of a transverse to the flow direction of the ridge, is cutting into this, it is called the antecedent. The Latin root word antec edere ( precede ) refers to the fact that the system of the river system of the uplift of the mountain range went forward in time. Examples of antezendente Talstücke are the Rhine at its breakdown through the Rhenish Slate Mountains, the Danube at the Iron Gate or the Ebro in Catalonia's coastal mountain range ( Cordillera Litoral). There arise, inter alia, the so-called gullies. Here, a locally each different uplift amount required to antecedent flow to lateral flexing within the mountain range.
