Simulation-Optimization Quantitative and qualitative model operation of aquifer in order to adjust pollutant concentrations using Cuckoo algorithm

Population growth and agricultural development and industrialization is causing the increasing need to use underground water resources. Hence, the quality of these resources is of particular importance. In some aquifers due to the Heterogeneous distribution of pollution resources, excessive centralized harvest in particular areas or gender difference in the aquifer, the water quality in different areas is highly variable. In these cases, In case of impossibility to eliminate contaminant, can be consistent with optimal policy operation pollutant concentrations as possible in the aquifer. In this study, a Simulation - Optimization model of groundwater were presented with the aim of minimizing the concentration gradient within the aquifer. The model of combining aquifer qualitative and quantitative simulation models with the cuckoo intelligent optimization algorithm in the MATLAB programming environment Was prepared. Simulation – optimization model was performed for a five-year period in the study area. The results showed EC concentration differences in selected wells with optimal harvest policy compared to the current harvest policy, had decreased to 12 percent. Also with comparing the initial EC values and EC values after optimization, was observed that the concentration values considerably had decreased in wells places. Further can said that applying the present harvest policy in addition to adjusting the concentration gradient, reduces effectively EC values of the aquifer.
