River Migration Animation (IMAGE) University of Texas at Austin Caption A cartoon animation showing the relationship between river bend curves and river migration. While sharp bends cause higher rates of migration, the point of maximum migration occurs downstream from the maximum curvature of the bend. This creates a 'lag' between the point of maximum curvature and the point of maximum migration. Credit Zoltan Sylvester/ The University of Texas at Austin Bureau of Economic Geology.
