In Pre-Columbian chinampa agriculture, which limitation appears when drainage canals become excessively narrow?

💡 Explanation

Reduced canal width limits water flow, thus reducing the rate of nutrient replenishment via irrigation from lake sediments due to laminar flow; therefore nutrient availability drops rapidly, rather than the other benefits, because nutrient recycling depended on circulation.
