Which risk occurs when deflation exceeds deposition near coastal dunes?

💡 Explanation

Increased saltwater intrusion occurs because a lowering of the water table due to deflation exceeds groundwater recharge; therefore, saltwater replaces freshwater in the aquifer, rather that bedrock weathering or temperature/nutrient effects dominating.
