← HistoryDuring Abbasid-era irrigation projects, which mechanism limited canal network expansion?
A)Algebraic water allocation models✓
B)Differential gear speed calculation
C)Triangulation-based land surveying
D)Pythagorean theorem soil composition
💡 Explanation
Algebraic water allocation models determined permissible water flow, limiting each canal's draw in the system because maintaining equitable distribution to all users ensured the viability of upstream agriculture rather than unchecked expansion by wealthier landowners; therefore, algebraic control was used.
