Since the formation of the Black Forest and its foothills during the geological upheavals of the Upper Rhine Graben, the Wiese has shaped the landscapes in the Southern Black Forest and the Dinkelberg through its continuous erosion and sedimentation work. The Wiese flows through two topographically and geologically distinguishable sections, which divide the Wiesental valley into its upper reaches in the valley of the Schwarzwaldwiese between Fahl and Zell, and the Lower Wiesental valley in its lower reaches between Hausen and Kleinhüningen.
