Which risk dramatically intensifies when a coastal levee constructed on soft, compressible soil experiences prolonged tidal loading?

💡 Explanation

When prolonged tidal loading occurs on a levee built on soft soil, consolidation settlement progresses because the pore water is squeezed out, reducing the soil volume, further lowering the levee and increasing instability. Therefore, amplified levee settlement and instability increase compared alternatives such bioerosion, seismicity or biodiversity impacts which require different catalysts.
