Abstract
The numerical computations of flood flows with supercritical flow region due to the constraction of flow by a groin have been made. In order to compute flood flows under both super-and subcritical flow conditions, TVD finite difference scheme based on the MacCormack explicit method is applied. In order to compute a cofficient of eddy viscosity, the depth averake κ-ε model is used. The influence on the errors introduced by TVD are examined from the points of the grid-size, giving the local or global time interval. It is found out in comparisons with computed and observed data that the supercritical flow regions is computed smaller if the size of recirculating flow is underestimated. On the other hand, the predicted supercritical flow region has a good agreement with experimental results if the recirculating flow area is estimated well.
