East Coast of India in the context of "Kaveri"

Andhra Pradesh is a state on the east coast of southern India. It is the seventh-largest state and the tenth-most populous in the country. Telugu, one of the classical languages of India, is the most widely spoken language in the state, as well as its official language. Amaravati is the state capital, while the largest city is Visakhapatnam. Andhra Pradesh shares borders with Odisha to the northeast, Chhattisgarh to the north, Karnataka to the southwest, Tamil Nadu to the south, Telangana to northwest and the Bay of Bengal to the east. It has the longest coastline in India (aerial distance between extreme ends) at about 1,000 kilometres (620 mi).

Archaeological evidence indicates that Andhra Pradesh has been continuously inhabited for over 247,000 years, from early archaic hominins to Neolithic settlements. The earliest reference to the Andhras appears in the Aitareya Brahmana (c. 800 BCE) of the Rigveda. Around 300 BCE, the Andhras living in the Godavari and Krishna river deltas were renowned for their formidable military strength—second only to the Maurya Empire in the subcontinent. The first major Andhra polity was the Satavahana dynasty (2nd century BCE–2nd century CE) which ruled over the entire Deccan Plateau and even distant areas of western and central India. They established trade relations with the Roman Empire, and their capital, Dhanyakataka, was the most prosperous city in India during the 2nd century CE. Subsequent major dynasties included the Vishnukundinas, Eastern Chalukyas, Kakatiyas, Vijayanagara Empire, and Qutb Shahis, followed by British rule. After gained independence, Andhra State was carved out of Madras State in 1953. In 1956, it merged with Telangana, comprising the Telugu-speaking regions of the former Hyderabad State, to form Andhra Pradesh. It reverted to its earlier form in 2014, when the new state of Telangana was bifurcated from it.

The Eastern Ghats is a mountain range that stretches 1,750 km (1,090 mi) along the eastern coast of the Indian peninsula. Covering an area of 75,000 km (29,000 sq mi), it traverses the states of Odisha, Telangana, Andhra Pradesh, Karnataka, and Tamil Nadu. The range forms a discontinuous chain of mountains along the eastern edge of the Deccan Plateau, stretching from north of the Mahanadi River in Odisha to Vaigai River in Tamil Nadu at the southern end of the peninsula. The Eastern Ghats meet the Western Ghats at the Nilgiris. The average elevation is around 600 m (2,000 ft) and Arma Konda is the highest peak in the mountains at 1,680 m (5,510 ft).

Geological evidence indicates that the mountains were formed during the archeozoic era and became part of the Indian subcontinent post the break-up of the supercontinent of Rodinia and the formation of Gondwana. The mountains were formed through further metamorphism during the mid-Proterozoic era. The northern section of the range has an elevation ranging from 900–1,400 m (3,000–4,600 ft) and lies mostly in Odisha. The middle section stretches up to the Penna River and consists of two parallel ranges with an average elevation of 520 m (1,710 ft). At the southern end, the range is made up of several smaller hills.
