India’s river network is broadly classified into two categories based on their origin: the Himalayan rivers and the Peninsular rivers. While the Himalayan rivers are perennial, the Peninsular rivers are seasonal and rely primarily on rainfall.

Classification of Rivers
Understanding the hydrological and geographical characteristics of these rivers is essential. The following table breaks them down into five main categories:
| Category | Examples | Key Features |
|---|---|---|
| Himalayan | Ganga, Indus, Brahmaputra | Snow-fed, perennial, deep valleys. |
| Peninsular | Godavari, Krishna, Narmada | Rain-fed, seasonal, broad valleys. |
| East-flowing | Mahanadi, Kaveri, Pennar | Flow into Bay of Bengal, form deltas. |
| West-flowing | Narmada, Tapi, Sabarmati | Flow into Arabian Sea, form estuaries. |
| Inland Drainage | Luni | Disappears in Rann of Kachchh. |
Major Himalayan River Systems
These rivers originate from the Himalayas and act as the backbone for irrigation and hydropower in North India. Key details are summarized below:
| River | Source | Mouth | Key Facts |
|---|---|---|---|
| Indus | Tibetan Plateau | Arabian Sea | Forms deep gorges in Ladakh. |
| Ganga | Gangotri Glacier | Bay of Bengal | Longest river in India. |
| Brahmaputra | Angsi Glacier | Bay of Bengal | Flood-prone, forms braided channels. |
| Yamuna | Yamunotri Glacier | Prayagraj | Right-bank tributary of the Ganga. |
Peninsular River Systems: Tips to Remember
To keep track of the major east-flowing rivers, you can use the acronym “G-K-M-K” (Godavari, Krishna, Mahanadi, Kaveri). These rivers serve as the lifeblood of the southern plateau.
| River | Source | Key Features |
|---|---|---|
| Godavari | Trimbakeshwar | Longest peninsular river, known as ‘Dakshin Ganga’. |
| Krishna | Mahabaleshwar | Important dams: Nagarjuna Sagar. |
| Narmada | Amarkantak | Flows through a rift valley. |
| Kaveri | Talakaveri | Known as the Ganga of South India. |
