The model of a tidal channel in a coastline study is scaled to 1/100 of actual size. Fresh water is to be used in place of seawater in the model. Assuming that the Reynolds number must be matched, what model velocity is needed to ensure dynamic similarity? Will similarity also be achieved for free surface effects related to the Froude number? In your calculations, note that the appropriate velocity and length scales for the actual tidal channel are V = 0.5 m/s and L = 10 m, respectively. (Same Re for both model and the prototype)
