← HistoryWhich outcome arises where intensive terraced agriculture causes significant modification of hillside hydrology?
A)Decreased overall regional erosion rates
B)Amplified downstream flood pulse peaks✓
C)Increased soil moisture conservation
D)Enhanced groundwater recharge rates
💡 Explanation
Flood pulses increase because terracing, while preventing surface erosion, compacts soil layers and reduces infiltration capacity, thereby increasing rapid surface runoff rather than groundwater absorption; therefore larger pulses, rather than reduced ones, are more likely.
