Which challenge commonly faced early canal engineers, given al-Karaji equations only approximated natural terrain?

💡 Explanation

Calculating excavation volume proved difficult because al-Karaji's *algebraic approximation* of irregular terrain introduced errors. This meant that volume estimates deviated considerably compared to true earth masses as they were measured, therefore impacting efficiency, rather than lock gate synchronization impacting water transfer delays.
