Abstract: An implicit, fully coupled, two-dimensional, free-surface flow numerical model has been developed to calculate bed changes in alluvial channels. Vertically averaged freesurface flow equations in conjunction with sediment transport equation are transformed into a non-orthogonal, boundary fitted coordinate system and then are solved numerically. The model is used to analyze problems of local scour around bridge abutments. Measured data are compared with computational results and satisfactory agreement is achieved.
