In recent years, a lot of river bridge decks have been washed away due to heavy rain. Our purpose is to investigate the velocity and pressure distributions characteristics around a bridge deck during overflow based on the experiments. The results showed that the velocity distributions are an asymmetric between the upper and bottom of a bridge deck. It is suggested that the flow velocity particularly has been developed on the bottom side. On the other hand, it has occurred the negative pressure on the bottom side during overflow caused by separation flow, and then, it is suggested that negative lift force affected on a bridge deck.
