Which optimization was achieved by al-Khwarizmi's algebraic techniques in irrigation system design within the Abbasid Caliphate?

💡 Explanation

Al-Khwarizmi's algebra allowed for calculating optimal canal routes by modeling water flow and land elevation, minimizing canal length because shorter canals reduce water loss through evaporation and seepage. Therefore, minimizing length was optimized, rather than efficiency, pressure, or flood amplitude prediction, which require different engineering approaches.
