is biggest river in south India. It rises at Talakaveri on the Brahmagiri range in the Western Ghats in Karnataka at an elevation of about 1341 m above mean sea level and flows for about 800 km, before its outfall into the Bay of Bengal. 

principal tributaries

The Cauvery river system consists of 21 principal tributaries each with catchment area around 250 sq. km. 

The river Bhavani

is one of the largest and the second longest river in the basin rises in Kerala and Karnataka but lies mostly in Tamil Nadu.


Hemavathi 

 The longest tributary, the Hemavathi (233 km) is the fifth largest river in catchment area and lies wholly in Karnataka. 

It rises in the Western ghats and runs South-East. After a stream from the West joins it, it turns East, receiving the Yagachi from the North. 

It then winds round Holenarasipur and runs South to the Cauvery near Yedatore. 


The Kabini river 

is an important tributary of the Cauvery. It is a perennial river, 150 to 200 m. wide and has a course of about 240 kms. It rises in the Western ghats in North Wynad in Kerala State as two streams i.e. the Mannantoddypuzha and Panamarampuzha. 

About 16 kms. below their confluence, the Kabini forms border between Kerala and Karnataka for about 12 kms. before entering Karnataka state. 

It joins the Cauvery at Tirumakudalu Narasipur (T.N.Pur) and this confluence point is being considered as a spot of great sanctity. 

The confluence point is also called as “Triveni Sangama”.


 The Bhavani

is a picturesque perennial river of South India, rising in Attappadi valley in Kerala. It enters Tamilnadu near Mannar and traverses from West to East for 234 kms. and joins the Cauvery near Bhavani Town. 

most important tributaries are Amravati, Hemavathi, Kabini, Noyil and Bhavani

It principally receives runoff from the South-West monsoon and occasional floods during North-East Monsoon. From the point of view of flow contribution to the system, apart from the head reach of the Cauvery main, the most important tributaries are Amravati, Hemavathi, Kabini, Noyil and Bhavani. 


All the distributaries in the region are non-perennial and flow is mainly due to Cauvery water release during June to January.


 No considerable flow occurs due to South-West monsoon and for most of the months in the year, the flow available are the regulated flows from upper regulators maintained by Tamil Nadu.

 The total length of the river Cauvery from the head to its outfall into the sea comprises a length of 320 km in Karnataka 416 km in Tamil Nadu and remaining length of 64 km forms the common boundary between states of Karnataka and Tamil Nadu (Table 3).
