Which risk increases when a levee system restricts sediment deposition on adjacent floodplains?

💡 Explanation

When levees prevent sediment deposition, the river's energy increases due to lack of natural floodplain energy dissipation causing greater erosion downstream because the river base level adjusts. Therefore, streambed incision risk increases, rather than upland porosity, decreased albedo, or weathering, all of which involve different geologic processes.
