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