Which consequence arises if pre-Columbian stone aqueducts lack maintenance?

💡 Explanation

Decreased water flow efficiency occurs because a phenomenon called 'biofilm accumulation’; biofilm increases surface roughness and diminishes hydraulic diameter and flow. Stagnation creates blockage rather than collapsing everything, and changing temperature, therefore flow rate falls.
