Determine the optimal design and implement Artificial Recharge Basins

Irregular groundwater consumption and not replacing it has reduced groundwater level in many of aquifers at Iran. So determination of suitable areas for artificial recharge is very important as a solution to this problem. The goal of this study is determination of artificial recharge basins location by fuzzy logic and then optimal design of these basins. The ratio of income to expense was used to selection of the basins best design. So, five height scenarios were defined. All of scenarios were simulated by HEC-HMS model and their income was determined as infiltrated water volume. Also, the expense of scenarios was calculated based on materials used in building basins. The results showed that the suitable areas for artificial recharge plan implementation are 0.86% very efficient and 4.7% efficient by fuzzy logic method. Also the best scenario is 2.5 m based on the benefit to cost ratio and 2m based on the benefits view.
