Webstream power, as afforded by the channel boundary conditions. These categories are further subdivided into components of the hydraulic geometry, i.e., stream power into modifiers of slope and depth; and boundary resistance into those stressors affecting the streambed and stream banks. Finally, stressors are WebStream and River Erosion. As a stream moves water from high elevations, like mountains, towards low elevations, like the ocean, which is at sea level, the work of the stream …
