Which risk dramatically increases when a levee system built on alluvial deposits undergoes repeated saturation cycles?

💡 Explanation

Levee saturation triggers consolidation through a process resembling squeezing, because water pressure lowers effective stress, therefore increasing system subsidence rates, rather than dust storms which stem from arid conditions, or sediment bio-availability/mineral concentration, which do not strongly rely on levees.
