Prediction of the initial impact force is a major task associated with flood damage assessment of structures subjected to flash flooding especially due to dam break and levee breach. Investigation of failure modes such as overturning and sliding due to soil scouring or erosion is not relevant if the structure first fails by the massive initial dynamic impact. Therefore, a careful assessment of the initial flood impact is critical for the design of structures and during the flood damage assessment process. In most of the past flood damage studies, total flood load acting on the structures was estimated by maximum velocities and water depths obtained from the two‐dimensional hydrodynamic model..
