Explanation:

The Barakar River is the main tributary of the Damodar River in eastern India. Originating near Padma in Hazaribagh district of Jharkhand it flows for 225 kilometres (140 mi) across the northern part of the Chota Nagpur Plateau, mostly in a west to east direction, before joining the Damodar near Dishergarh in Asansol, Bardhaman district of West Bengal. It has a catchment area of 6,159 square kilometres (2,378 sq mi). The main tributaries, Barsoti and Usri, flow in from the south and north respectively. Apart from the two main tributaries some fifteen medium or small streams join it.

The river flows in all fury during the rains in its upper reaches and has washed away two bridges constructed successively on the Grand Trunk Road. The great stone bridge across the river near Barhi, in Hazaribagh district, built around 1848, was washed away in 1913, after a fall of 250 millimetres (10 in) of rain in 24 hours.
