A two-dimensional numerical model for free-surface flows was constructed. The model was based on the high-resolution upwind scheme with MUSCL (Monotone Upstream-centered Schemes for Conservation Laws) technique, SMAC (Simplified Marker and Cell) method and a collocated grid system. The free-surface was treated by VOF (Volume of Fluid) method which was one of interface-capturing methods. The model was verified against experimental data of the dam-break flow propagating over a triangular bottom sill as well as flow at downstream from a groundsill. It showed that the model can reproduce the behavior of the dam-break flow and the flow at downstream from a groundsill.
