Every river is prone to change its course, and this is brought about by differential erosion of the bed-rock, climatic changes and eustatic and tectonic effects. Waterfalls, meanders, ox-bow lakes, river terraces, etc., are some of the most conspicuous land-forms thus created. The more powerful down-cutting streams in the mountainous tract often capture (river piracy) water of the less powerful adjacent streams and the valley of beheaded streams is often dry.
