Thalweg slope
Did you know?
WebIn hydrological and fluvial landforms, the thalweg is a line drawn to join the lowest points along the entire 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. WebIn these cases, scientists realized that the riverbed often tends to rise and fall with distance downstream relative to an average elevation of the river's slope. That led scientists to map the bed elevation down the deepest path …
