WebJun 8, 2024 · The stream gradient is the slope of the river channel. A steeper gradient promotes downward stream erosion. When tectonic forces lift up a mountain, the increased stream gradient causes the stream to erode downward and make a valley. Stream velocity is the speed of the flowing water in the channel. Webdevelop in areas where the rock (or unconsolidated material) beneath the stream has no particular fabric or structure and can be eroded equally easily in all directions. Examples: …
