The Purwa Falls is a waterfall on the Tamsa River in Rewa district in the Indian state of Madhya Pradesh.

It is located in Semariya, a town in Rewa district, near Basavan Mama, a sacred and tourist place.

After appearing from a pond in the Maihar district and While descending through the Rewa Plateau and draining northwards, the Tamsa makes a vertical fall of 70 metres (230 ft), creating the Purwa Falls.

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.
