According to Hindu mythology, Ganga flowed in the heavens but then was ordered to go down to earth. Fearing that her forceful descent might wash away the earth, the gods sought the help of Shiva. Shiva broke the fall of Ganga-Ganges by capturing her in his mighty locks. Since then, Ganga-Ganges resides on top of Shiva's head as his second wife, the first being Parvati.
The Ganges river basin is one of the most fertile and densely populated in the world and covers an area of 400 000 sq miles (1 000 000 sq km). The river flows through 29 cities with population over 100,000, 23 cities with population between 50,000 and 100,000, and about 48 towns.
