Which risk increases when a river's delta disperses into shallow coastal lakes?

💡 Explanation

Saltwater intrusion is elevated because reduced river flow and shallow lake depths allow more saltwater to penetrate inland through permeable sediments. Therefore, the aquifer contamination increases, rather than methane production, land uplift, ocean circulation effects.
