Power line
The streamline is the line connecting the points with the highest flow velocity at or just below the surface of a river .
Its location depends on the shape and roughness of the banks and the river bed, as well as the internal friction of the water body. On straight sections of the river it is usually roughly in the middle and is shifted by centrifugal force in bends to the outside of the bend. The position of the stream line also changes with the amount of water that flows in a river bed, since with the changed water level a different river cross section with changed discharge conditions is used by the water.
The position of the stream line is usually not identical to the valley path , the line connecting the lowest points of the transverse profile in the longitudinal direction of a flowing water.
