Which phenomenon exacerbates collapse-sinkhole formation during intense rainfall on karst?

💡 Explanation

Increased water infiltration causes increased soil bulk density because greater total weight promotes downward forces, driving subsidence via mechanical compaction and dissolution. Resulting overburden stresses cause sinkhole collapse, where increased bulk increases loads, rather than hydraulic unloading.
