- Geum River

It is 394.79km in length and covers 9,912.15§´.  It is a combination of 20 variously sized tributaries, including Bocheongcheon (ÜÃôìô¹) from east of Okcheon, Mihocheon (Ú¸ûÉô¹) from south of Jochiwon, and Chogang (õ®Ë°) and Gapcheon (Ë£ô¹).  It is an incised meander in upstream and forms various valleys such as Mujugucheondong in Muju and Yangsanpalgyeong (åÕߣø¢ÌØ) in Yeongdong.  During the rule of Buyeo, the downstream was called Baengma River and created Nakhwaam that is known for its contribution to the fall of Baekje by eroding Mt. Buso.

From Ganggyeong to the river mouth, it forms a drowned valley (ìÊÍÛ) to empower the developments of ports in Gunsan and Ganggyeong.  Small boats could travel to Bugang through inland canals, but are not used today following the development of Honam Railway and ground transportation.  There are Daejeon Basin and Cheongju Basin by upstream, Hoseo Plains (ûÉà¤øÁå¯:Ò®øÝøÁå¯) by midstream, and Jeonbuk Plains by downstream to be known as Korea¡¯s leading rice producer along its course.

With the development of seaborne transportation and agriculture, old commercial cities, including Gongju, Buyeo, and Ganggyeong, rose early in Korean history.  In 1980, Daecheong Multipurpose Dam was constructed near Shintanjin.  As it is located in the center of the Korean Peninsula, it has moderate climate with the average temperature of 11.0~12.5¡É and annual precipitation of 1,100~1,300mm.
