Miryang's geography is heavily influenced by the two rivers which flow through it, the Miryang and Nakdong Rivers. All of Miryang lies within the Nakdong basin, and the Nakdong River itself runs along Miryang's southern border. The city's topography generally slopes from the high peaks of the Yeongnam Alps in the northeast to the Nakdong valley in the southwest. Much of the city is drained by the Miryang River, which rises in western Ulsan and flows through the city center to join the Nakdong at Samnangjin. Portions are drained by other Nakdong tributaries, including the Naejincheon.
