River Capture :

It is a natural process which is more active in the youthful stage of the valley development of a river because the streams during this stage are actively engaged in headward erosion and valley lengthening.
However, river capture also occurs during mature and senile stages of the valley development through the process of lateral erosion and meander intersection.
The stronger and more powerful streams (in terms of channel gradient, stream velocity and discharge and kinetic energy) capture the upper courses of weak and sluggish streams.
The diversion of the part of the course of a river by another river is called stream diversion or stream capture or stream piracy.
The river which captures the course of another river is called the capturing or captor stream while the part of the stream which has been divested of its course and water is called the captured stream.
Saraswati River was captured by the Yamuna River through the Process of headward Erosion.
