The Ganges, Godavari, Irrawaddy, and Krishna are all rivers that flow into the Bay of Bengal. The Ganges is a trans-boundary river in India and Bangladesh, and is considered sacred by Hindus. The Godavari is the second longest river in India, and is also known as the Dakshin Ganga. The Irrawaddy is the largest river in Myanmar, and is an important source of irrigation and transportation. The Krishna is the fourth longest river in India, and is also known as the Kaveri. All four rivers eventually flow into the Bay of Bengal, which is an inlet of the Indian Ocean.
