Abstract

Details of a numerical model development for investigating the amount of BACKWATER due to a cylindrical pier in subcritical flows are presented in this paper. The governing equations were discretized using the FINITE DIFFERENCE METHOD and the Mac Cormack's technique, was used to solve the difference equations. In order to discretize the computational domain, a non-uniform grid was used and the SYMMETRICAL MIRROR conditions were employed for the solid boundaries. The numerical model results were finally compared with the corresponding results of empirical formula and a very good agreement has been achieved. Also, it is generally found that by increasing the Froude number of downstream flow, the BACKWATER increased at the upstream of pier.
