Hydrauric Analysis On Water Stage Change Along The Submerged Weir And Tides Effect In Han River, Suk-Hwan Jang, Ji-Hwan Oh, Hong-Soo Kim, Man-Kyu Song, Dal-Sik Woo

International Conference on Hydroinformatics

Sinkok submerged weir in Han river, Seoul Korea was built in early 1980’s for the purpose of water level maintenance and protection from sea water intrusion from the estuary. Its length is almost 1 km and 2.4 meter height which has two composite structures of rigid and movable weir. Huge wetland developed as the results of weir construction just down to the weir. However, recently social conflicts for the weir removal occurred for the river rehabilitation and aqua-eco system recover. This study focused on hydraulic analysis, especially water level changes in terms of with and without submerged weir along the …
