Question

The river Kaveri splits into many branches before falling into the Bay of Bengal, why?​

Answer 1

over 90% of the water carried by the Indian rivers into the Bay of Bengal: the rest is drained into the Arabian sea or forms inland drainage.

This lop sided distribution is due to the location of the watershed separating the drainage systems falling into the Bay of Bengal and the Arabian sea.

This 2,736km long watershed runs from Kanniyakumari through the western ghats, the Ajantas, the Maikala, the Vindhayas and the Aravalis range to the Shiwalik hills near Haridwar

Also, the other reason, during the cenozoic times, the India Plateau witnessed 4 localized tectonic events one of which was formation of western Ghats. It was due to the rupture and activation along one of the triple junction arm. The western Flank of the plateau subsided forming the Arabian Sea with its broad continental shelf. the eastern flank tilted east and northwards, forming the western Ghats. this made the plateau a uplifted horst.

The slope of the plateau forms the course of peninsular rivers : Mahanadi, Godavari, Krishna, Kaveri which are east flowing into the Bay of Bengal whereas the rivers along the western slopes of western ghats are short, swift; Also, rivers such as Son and tributaries of Yamuna ( Betwa, Singh, Ken, Chambal system), are all northward flowing rivers.
