Which risk increases when rapid river incision exposes unconsolidated levee sediments during channel migration?

💡 Explanation

When incision exposes unstable levee material, slope instability occurs because reduced support and increased pore pressure lead to landslides and slumps threatening the levee integrity. Therefore failure via mass wasting results, rather than other phenomenon like altered floodplain dynamics focused on sediments, carbon or geochemical processes instead of structural issues.
