Abstract:

This study shows the applicability of using a numerical sedimentation model to analyze various problems related to flood-control design in an alluvial river. Problems concerned with maintaining excavated channels and evaluating dredging requirements were analyzed. The effect of increased channel capacity due to channel scour during the passage of flood peaks was evaluated. Careful adjustment and verification of the numerical model using measured data were critical to the success of this application.
