Budget constraints in water resource management agencies often mean a reduction in the number of observation wells included in a monitoring network. Due to economic considerations and reducing monitoring costs, the optimization approach in this study is to reduce the monitoring stations. In the present study, genetic algorithm was used to designing optimal water level monitoring network. The aim of optimization to determine an optimal combination (reduced) from the main network was well observed, so that the possibility of measurement error smallest and least loss of data and provide the best distribution of wells. Using the genetic algorithm, the groundwater monitoring network of the region was optimized. Using the genetic algorithm, the groundwater monitoring network of the region was optimized. In Koohdasht Plain, among of  15 observation wells, 13 wells observations had data. in order to do this research, the data for 36 consecutive months, namely, data from 1392 to 1394 were used. Using the genetic algorithm, the groundwater monitoring network was redesigned and selected wells were selected from potential points. finally, 28 wells had the lowest RMSE of  0.113 and had the best distribution. Location of wells obtained by a number of existing wells was near. The results obtained with the criteria of the quantity of groundwater monitoring network design, which corresponded to show the effectiveness of this approach. %U https://ije.ut.ac.ir/article_68668_bf650c187b74f434b0e6a2a2d44570d0.pdf
