Which consequence results when arid region alluvial fans heavily develop?

💡 Explanation

The expansion of alluvial fans leads to increased impermeable areas caused by sediment compaction following rapid deposition through the mechanism of sediment aggradation; because runoff concentrates, downstream flash flood magnitude increases therefore, this is the most direct consequence rather than the impacts on other systems.
