Which risk increases as seasonal flooding deposits alluvial layers upon coastal infrastructure?

💡 Explanation

Accelerated subsidence increases because layers of alluvial deposits compress under their own weight via the mechanism of sediment consolidation; therefore the infrastructure will subside, rather than experience enhanced stability from novel ground structures.
