Sohlenkerbtal

A Sohlenkerbtal is a type of valley characterized by steep slopes and a broad valley floor. This specific valley form develops under the influence of groundwater flow. The term "Sohlenkerbtal" is German, meaning precisely a valley with these characteristics.1

Valleys are primarily formed by the erosive action of rivers, which cut down into the landscape. Hillslope processes also contribute to shaping the valley sides. The ultimate baselevel for rivers is typically sea level, though local baselevels like lakes or dams can also influence their erosion.1

While rivers tend to form V-shaped valleys, glaciers can reshape these into a characteristic U-shaped cross profile. This is due to glaciers eroding the bedrock along the base and lower sidewalls of the valley more extensively than streams do.2
