A is a vegetated piece of land. B is a concrete piece of land. Is A or B more prone to flooding  / more likely to flood?

• A, because vegetation is LESS permeable = lower infiltration = more surface runoff = greater risk of flooding
• B, because concrete is LESS permeable = lower infiltration = more surface runoff = greater risk of flooding
• B, because concrete is MORE permeable = lower infiltration = more surface runoff = greater risk of flooding
• A, because vegetation is MORE permeable = lower infiltration = more surface runoff = greater risk of flooding
