The Damodar River originates from the Hazaribagh plateau in the Chhota Nagpur region and flows eastwards. This river is significant in the geography of eastern India, particularly flowing through the states of Jharkhand and West Bengal before joining the Hooghly River.

The Hazaribagh plateau is part of the larger Chhota Nagpur Plateau, which is known as the "Ruhr of India" due to its rich mineral resources. The Damodar River valley is especially important for coal mining and industrial activities.

Key characteristics of the Damodar River:

• Origin: Hazaribagh plateau, Chhota Nagpur
• Direction of flow: Eastwards
• Major tributaries: Barakar, Konar, Bokaro
• Ends by merging with the Hooghly River near Kolkata
• Historically known as the "River of Sorrow" due to frequent flooding, now controlled by dams under the Damodar Valley Corporation (DVC)

Among the options provided:

• Bhima: Tributary of Krishna River, flows in Maharashtra and Karnataka
• Damodar: Correct answer - originates from Hazaribagh plateau
• Amravati: Tributary of Kaveri River, flows in Tamil Nadu
• Ghatprabha: Tributary of Krishna River, flows in Karnataka

Important Formulae

While this is primarily a geographical concept, some relevant calculations include:

River length: $L=L_1+L_2+L_3+\cdots +L_n$

Where L represents total river length and L₁, L₂, etc., represent segments of the river's course.

Drainage basin area: $A=\int dA$

Where A represents the total area of the river's drainage basin.
