2018-06-11 · Rates of headward erosion and channel lengthening vary between different streams, because some streams will have steeper valleys, resulting in faster water flow rates and faster erosion. In some cases, this results in a phenomenon called stream piracy, in which part of the drainage of one stream is captured by another, faster-eroding stream.
