For the design of a groundsill, it is important to estimate the depth and area of local scour around it. In this study, we intend to construct a numerical simulation model which calculates a 2-dementional flow with MacCormack scheme and computes bed elevation by considering the non-equilibrium sediment transport. The result of calculation by this model is compared with the data observed from the hydraulic model test and they show rather good agreement.
