Which outcome occurs when wind exceeds saltation threshold affecting coastal dunes?

💡 Explanation

Migration of the dune system occurs when the saltation threshold is exceeded, because particle entrainment increases leading to sediment transport shifting the dune; therefore migration happens, rather than stabilization outcomes under other conditions.
