Explanation:

Chachai Falls is in Rewa district in the Indian state of Madhya Pradesh. It is the 23rd highest waterfall in India. The Chachai Falls is on the Bihad River, a tributary of Tamsa or Tons River as it comes down from the Rewa Plateau. It has a total height of 130 metres (430 ft). Chachai Falls is an example of a nick point caused by rejuvenation. Knick point, also called a nick point or simply nick, represents breaks in slopes in the longitudinal profile of a river caused by rejuvenation. The break in channel gradient allows water to fall vertically giving rise to a waterfall. It is situated 46 kilometres (29 mi) from Rewa, at the edge of the Chitrakoot Hills, a part of the Kaimur Range
