... is the variation in velocity calculated across a distance of x . The three water surface gradients considered of 2/1000, 5/1000 and 10/1000 are intended to simulate three different acceleration magnitudes. The uniform flow condition represents a no-acceleration condition. To assess the velocity structures...
