Which outcome arises when rapid freshwater influx occurs in a coastal karst aquifer system?

💡 Explanation

Increased sinkhole collapse frequency occurs due to freshwater's lower density and dissolving power altering the hydraulic head and subterranean support; this is Conduit flow dissolution. Subsequently the structural integrity weakens because freshwater is less saturated with carbonate, therefore sinkholes form rather than increased sediment deposits impacting biodiversity.
