River rejuvenation
In geomorphology a river is said to be rejuvenated when the base level that it is flowing down to is lowered. This can happen for various reasons.
==Signs==
Rejuvenated terrains usually have complex landscapes because remnants of older landforms are locally preserved. Parts of floodplains may be preserved as terraces along the downcutting stream channels. Meandering streams often become entrenched, so a product of older river systems is found with steep, very pronounced "V" shaped valleys - often seen with younger systems.
