Which risk increases when a levee, constructed from cohesive soil, is rapidly saturated by floodwater?

💡 Explanation

When a cohesive soil levee is rapidly saturated, increased pore water pressure reduces effective stress between soil particles, potentially triggering liquefaction because strength decreases. Therefore liquefaction risk increases, rather than erosion/seepage/desiccation which correlate to different soil-water interactions within the levee structure.
