Abstract
Jhoukou River is one of the branches of the Laonong River, and the most featured fluvial form is ingrown meander. Because of the strongly erosion along the Jhoukou River, there are some traces of channel migration. In this study, the channel centerline drawn from the air photos and SPOT satellite images is used to discover how the river changed and find out how landslides affect the meander. As for landslides, we use different SPOT satellite images to compute landslide ratio including typhoon Herb(1996), typhoon Bilis(2000), typhoon Toraji(2001), typhoon Mindulle(2004), and typhoon Haitang(2005). Sediment discharge during typhoon Mindulle is the lowest , and during typhoon Herb is the highest , respectively 0.36 Mt/y and 3.94 Mt/y. The average sediment discharge is 1.33 Mt/y from 1989 to 2005.
