Artificial recharge methods of Kariz

Kariz is one of the Iranian traditional water harvesting systems. Unfortunately some experts believe that water loss during winter and out of the crop season is the main disadvantage of this method. One of the methods to increase the discharge of kariz, is to recharge the aquifer artificially, where the karez tunnels are dug in them. This can be done by different methods, which are divided by "surface recharge " method and "underground recharge " method. Some case studies of Iran will be considered in the paper. Description of work One of the methods to increase the discharge of kariz, is to recharge the aquifer artificially, where the kariz tunnels are dug in them. This can be done by different methods, which are divided by "surface recharge " method and "underground recharge " method. 1. Surface recharge methods: Building the water-stopping facility on the ground in the aim of holding rainfall or surface water is called surface artificial recharge. In the surface recharging methods, water was spread and held on the ground, gradually infiltrating the underground and reaching the water table
