Which consequence results when decreased flood frequency occurs in an alluvial river system?

💡 Explanation

Reduced flood frequency minimizes sediment deposition and its sorting; reduced sorting creates poorly drained soils because particle sizes are not separated effectively by hydraulic sorting. Therefore, option A, rather than other hydrologic or ecological alternatives, becomes correct.
