What are their names?
 The two main river systems of the state are the Krishna and its tributaries, the Bhima, Ghataprabha, Vedavathi, Malaprabha, and Tungabhadra, in the north, and the Kaveri and its tributaries, the Hemavati, Shimsha, Arkavati, Lakshmana Thirtha and Kabini, in the south. Most of these rivers flow out of Karnataka eastward, reaching the sea at the Bay of Bengal.
