The stability of the river in the restored river is an important issue in maintenance and management. Bedelevation change simulation can be an effective way to predict the direction of river restoration by predicting longand short term bed elevation change of river. A 2D numerical model (CCHE2D) was implemented to simulate thelong-term bed elevation change. The study area is located in the Cheongmi-Cheon Notap-ri and 1.2 km long. Theflow scenario was constructed using the flow data that was measured at the water level observatory locatedupstream at the Janghowon Bridge. The bed elevation change pattern according to restoration of abandoned channelwas analyzed and the stability of river was evaluated. |
