Within the elevated aqueducts associated with Aztec chinampa agriculture, which risk increased sharply if water flowrate exceeded capacity?

💡 Explanation

Erosion undermines aqueduct integrity because increased flow causes greater shear stress against the canal walls, causing material loss due to hydraulic scouring. Therefore the system degrades from the base up, rather than weed expansion affecting water flow.
