Indus- Sutlej- Sarasvati- Yamuna: The Yamuna earlier flowed into the Ghaggar-Hakra River (identified with the Sarasvati River) and later changed its course due to plate tectonics.The new course dug its way through the so-called Barmah Choke and captured the lower course of the Goulburn River for 500 km (310 mi). Barmah Choke: About 25,000 years ago, an uplift of the plains near Moama on the Cadell Fault first dammed the Murray River and then forced it to take a new course.
The Kaituna and Pelorus rivers, New Zealand: About 8,000 years ago, a single river was divided by sea water to form two rivers.The now-dry valley of the original stream is known as a wind gap.Ĭapture mechanisms Sea level rise
The additional water flowing down the capturing stream may accelerate erosion and encourage the development of a canyon (gorge). The Maumee, flowing north-east, has broken into part of the Wabash River basin, capturing west-flowing streams and reversing their flow direction on entering it.
