Narmada River

The Narmada River is a major waterway in central India.

It is the fifth longest river in the country. It is also the longest river that flows from east to west. This means it drains into the Arabian Sea rather than the Bay of Bengal. The river is often called a lifeline for the states of Madhya Pradesh and Gujarat.

It provides essential resources to the people living in these regions.

The river begins at the Amarkantak Plateau in the Anuppur district.

Specifically, it rises from a small reservoir called the Narmada Kund. From this source, the water descends from Sonmuda. It falls over a cliff to create the Kapildhara waterfall. The river then follows a winding or tortuous course through hills and rocks. It passes the ruined palace of Ramnagar before moving toward Jabalpur. Near Jabalpur, the river falls again at the Dhuandhara waterfall. This name means "the fall of mist."

After the Dhuandhara falls, the river enters a unique geological feature. It flows through a narrow channel of magnesium limestone and basalt rocks. These are known as the Marble Rocks.

In this section, the river is compressed from a width of 90 meters down to only 18 meters. Beyond these rocks, the Narmada flows through three narrow valleys. These valleys sit between the Vindhya ranges in the north and the Satpura range in the south. This specific type of valley is called a rift valley. Unlike many other rivers, a rift valley river like the Narmada forms an estuary instead of a delta.

Geologists believe the Narmada valley formed through complex earth movements. About 160 million years ago, the supercontinent Pangea broke into two masses. These were Laurasia in the north and Gondwana in the south. The Narmada Valley is a graben. A graben is a block of the Earth's crust that dropped down between two higher blocks. These higher blocks are called horsts. The Narmada North and South faults mark the boundaries of this block. Some scientists suggest the Narmada and the Tapti rivers were once joined. They may have split due to recent movements in the Earth's crust.

The Narmada basin covers a massive area of 98,796 square kilometers.

Most of this land, about 82%, is located in Madhya Pradesh. Gujarat holds 12%, Maharashtra holds 4%, and Chhattisgarh holds 2%. The basin is divided into five physiographic regions. These include upper hilly areas, upper plains, middle plains, lower hilly areas, and lower plains. The land is very useful for humans. About 60% of the basin is arable land used for farming. Another 35% is covered in forest. The river has 41 tributaries. The Tawa is the largest of these tributaries.

The river is also deeply significant in Hinduism. Many people view the Narmada as a goddess. The name Narmada is Sanskrit for "The Giver of Pleasure." According to the Rewa Khand, the river was created from the perspiration of the god Shiva. Other legends say it formed from the teardrops of Brahma. The river is also known as Reva because of its leaping motion over rocks. People worship at many sacred sites along its banks. Omkareshwar is an important place of worship for Shiva.

Visitors also look for banalinga. These are white quartz pebbles shaped like a linga. They are found on the river bed and are considered sacred personifications of Shiva.

The river's environment changes as it flows toward the sea. In the upper regions, it receives heavy rain between 1,000 mm and 1,850 mm annually. This creates lush green vegetation. In the lower regions, rainfall drops to between 650 mm and 750 mm. This causes the plants to change into dry deciduous teak forests. As the river reaches Gujarat, it flows through the rich plains of Bharuch. The river becomes much wider here. It reaches a width of 3 km near Bharuch. Finally, it forms a 21 km wide estuary at the Gulf of Khambhat.
