The behavior of the flood flows in a floodplain with structures and hydrodynamic force acting on structures are investigated experimentally and numerically. The depths and the surface velocities of flood flows are measured by using image analysis and PTV, respectively. The hydrodynamic force is determined by a special device based a 2-component load cell. The model verifications of a numerical model based on FDS technique and unstructured FVM for 2D flood flows (FUF-2DF model) against these experimental data are made. It shows that the model can reproduce the complex behavior of flows and hydrodynamic forces acting on structures with reasonable accuracy.
