Which outcome occurs when floodplains lack riparian vegetation?

💡 Explanation

Higher flow shear mobilizes more sediment because riparian vegetation normally dampens the flow thereby decreasing sediment capacity via Filtration. Greater sediment reaches levees, increasing its vertical growth rate; therefore transport is accelerated, rather than the floodplain's slower accumulation.
