Hyeongsan River
The Hyeongsan River is a river in southeastern South Korea. It flows from Baeyanggol Valley (배양골), Wolpyeong-ri (월평리/), Dudong-myeon (두동면/), Ulju County in Ulsan to the Sea of Japan, covering a distance of about 62 km. The Hyeongsan watershed covers roughly 1,167 km² (Jo 1987:35). The Hyeongsan flows north from near the northern border of Greater Ulsan into Gyeongju city, where it enters the Gyeongju Basin and is joined by the Bukcheon stream (북천/), a major tributary. It continues north into Pohang city, and in Angang-eup of Pohang it is joined by the Gigyecheon flowing from the north and turns abruptly eastward. From there runs east and slightly north until it meets the Sea of Japan at Pohang Harbor. The estuary of the Hyeongsan has been covered by the massive industrial development around the port of Pohang, including the POSCO steel mill. History The Hyeongsan is primarily notable for the Silla civilization which arose within its valley, centered at Gyeongju. Middle Jeulmun Pottery Period potsherds have been unearthed in the Hyeongsan Basin. Several significant Mumun settlements arose along the river after 1100 BC, notably Wolsan-ri and Hwangseong-dong (FPCP 2005; GNRICH 2003). Economy Today the Hyeongsan continues to play a role
