In hydrological and fluvial landforms, the thalweg is a line drawn to join the lowest points along the length of a stream bed or valley in its downward slope, defining its deepest channel. The thalweg thus marks the natural direction (the profile) of a watercourse.

The meaning of THALWEG is a line following the lowest part of a valley whether under water or not.

What is a Thalweg? A thalweg is a term used in geography and hydrology to describe the line that follows the lowest points along the length of a riverbed or valley. This concept is crucial for understanding river dynamics, navigation, and even international boundaries.

In hydrological and fluvial landforms, the thalweg is a line drawn to join the lowest points along the length of a stream bed or valley in its downward slope, defining its deepest channel.

In international law, there’s a principle that if the border between two countries is a waterway, its thalweg marks the boundary line.

A term of German origin meaning originally the way (weg) of the valley (tal), the word Thalweg was spelt with an “h” before the 1902 German orthographic reform. Since it was adopted into geomorphologic literature before 1902, the older spelling is still sometimes preferred.

A thalweg is the center of the principal navigable channel of the waterway (which is presumed to be the deepest part). If there are multiple navigable channels in a river, the one principally used for downstream travel (likely having the strongest current) is used.
