Abstract: The Qanat (Karez) system is an ancient and ingenious hydraulic engineering method widely distributed in arid regions of Asia. By utilizing low-energy gravity-fed water supply and underground channels, this system significantly reduces water evaporation, providing sustainable water resources for ancient inhabitants. This study focuses on the Qanat system in Asian arid regions, analyzing its geographical adaptability through Geographic Information System (GIS) and evaluating how terrain, geomorphology, soil, and water resource conditions impact its distribution, while also exploring the cultural landscape aspects through historical documentation. The study anticipates uncovering the system’s adaptability under various geographic conditions and assessing its potential applications in modern arid region water management as well as its sociocultural significance. This paper highlights the ecological friendliness and low-energy requirements of the Qanat system, which provide a valuable framework for modern groundwater management. Particularly amidst climate change and global water scarcity, the Qanat system illustrates the sustainable value of ancient water management practices.
