Difference Between Himalayan and Peninsular Rivers

Main Difference – Himalayan vs Peninsular Rivers

Himalayan and peninsular rivers are two types of rivers that flow through India. These two classifications are based on the origins of the rivers; Himalayan rivers originate from the Himalayan ranges whereas peninsular rivers start from the peninsular. The main difference between Himalayan and Peninsular Rivers is their size; Himalayan rivers are larger and longer and carry a greater volume than peninsular rivers.

What are Himalayan Rivers

Himalayan rivers are the rivers that originate from the Himalaya mountain ranges. Indus, Ganga, and Brahmaputra are Himalayan Rivers. All these rivers originate from the Himalayas and flow towards the west. These rivers have many special characteristics compared to other river types in India.

Himalayan rivers have long valley lengths and larger channels. They also have larger basins and catchment areas. For example, the basin area of Indus river is 165 million km² whereas Godavari, the largest peninsular river, has a basin area of 312,812 km². Himalayan rivers are perennial (continuous water flow throughout the year) in nature and are fed by both rain and ice. Thus, they are very useful for irrigation. Himalayan rivers are considered to be antecedent streams, which maintain their original course although the underlying rock topology changes. They are also believed to be in their early maturity stage based on their volume, velocity, and other features. Himalayan rivers also form meanders and change their course, unlike peninsular rivers. The mouth of these rivers form large deltas; Ganga-Brahmaputra delta is the biggest delta in the world.

What are Peninsular Rivers

Peninsular rivers are the rivers that originate from the peninsular plateau of India. Kaveri, Narmada, Tapi, Krishna, Godaveri, and Mahanadi are some examples of peninsular rivers. Peninsular rivers are comparatively shorter and smaller than Himalayan Rivers. They also have smaller basins and catchment areas.

Peninsular rivers are consequent rivers, i.e., they follow the direction of the slope of the land. They are also seasonal or non-perennial in nature since they only receive water from the rain, resulting in a non-continuous water flow. These rivers flow through shallow valleys compared to Himalayan Rivers, and these areas are not easily erodible.  The flood plains of peninsular rivers are narrow.

Peninsular rivers are also believed to be older than Himalayan Rivers since they are in their maturity. The alluvial nature and the hard rock surface of the plateau don’t allow the formation of meanders. Some of these rivers such as Mahanadi, Godavari, and Krishna form small deltas whereas others like Narmada and Tapi form estuaries.
