Which risk increases for canal design, relying largely on physical understanding without the symbolic algebra perfected later?

💡 Explanation

Inaccurate water flow arises because symbolic algebra allows for more precise modeling of complex fluid dynamics than purely physical intuition, therefore flow estimate risk from simplified models increases, rather than just materials or construction estimates.
