Interfluve

An interfluve is a narrow, elongated and plateau-like or ridge-like landform lying between two valleys. More generally it is an area of higher ground between two rivers in the same drainage system. Interfluves are created by earth flow, also called solifluction, and they can also be former river terraces that were later bisected by fluvial erosion. Where younger sedimentary beds such as loess or colluvium have been laid down, the interfluves look rounder and less rugged. A consequence of interfluve formation is what is called an interfluvial landscape. Examples named in the article include parts of South Burgenland and the East Styrian Hills in Austria, much of the Iller-Lech Plateau in Bavarian Swabia and Upper Swabia, the Danube-Tisza interfluve and the Volga-Ural interfluve. Related terms include the doab, the land between two rivers.
