← HistoryWhich outcome resulted from increased hydrostatic pressure within early Persian Qanat systems?
A)Reduced waterborne iron impurities
B)Elevated mineral sediment accumulation✓
C)Improved summer temperature regulation
D)Decreased dissolved sulfur concentration
💡 Explanation
Increased hydrostatic pressure in Qanats lead to faster water flow and greater sediment carrying capacity, resulting in elevated mineral sediment deposition because increased flow erodes more material, therefore, sediment accumulation increased, rather than purifying the water.
