This report deals with validation of the calculation formula of wave crest velocity considering nonlinearity of seismic-induced sloshing response. The wave crest velocity is required for estimating the sloshing wave crest impact pressure. The calculated velocities by using the formula are compared with those based on the measured and computed results of wave height responses.
