Which outcome decreased hydraulic head beyond its limits for irrigation in Inca terrace farming?

💡 Explanation

Reduced irrigation effectiveness happened because decreased head meant lessened hydraulic pressure reduces flow. Specifically hydraulic jump, created backflow conditions that reduced flow to upper terraces ,therefore inhibiting water delivery, rather than directly eroding walls but nutrient leaching also remained high
