Karez system

The Karez system is an ancient method of irrigation that originates from Persia, now Iran, and is used in arid regions. It involves digging underground tunnels that direct groundwater from mountain aquifers to surface channels, reducing water evaporation and ensuring a steady supply of water for agriculture and communities. The tunnels are carefully constructed to follow the natural slope of the land, allowing water to flow by gravity. This system efficiently conserves water, prevents drought, and supports sustainable farming in dry environments. It’s a remarkable example of low-impact, eco-friendly water management.
