Which outcome limited long canal construction for Pre-Columbian chinampas?

💡 Explanation

Chinampas relied on shallow canals; longer canals experienced disproportionately increased evaporation. This is due to increased *surface area*, because evaporation scales with exposed liquid surface, therefore severely long canals were impractical, rather than nutrient depletion being the driver.
