ABSTRACT Due to climate change and urban growth, the demand for new freshwater sources, especially groundwater, is increasing in water-deficient countries like Iran. Therefore, this study aimed at groundwater potential mapping (GPM) of the Nahavand Plain, Iran, using an optimized adaptive neuro fuzzy inference system (ANFIS) in a geographic information system, with three metaheuristic optimization algorithms: differential evolution (DE), particle swarm optimization (PSO) and ant colony optimization (ACO). A spatial database was constructed using 273 spring locations and 14 groundwater conditioning factors. The optimization algorithms were evaluated using the receiver operating characteristic (ROC) technique. The ANFIS-DE, ANFIS-PSO and ANFIS-ACO models resulted in accuracy of 0.816, 0.809 and 0.758, respectively; the high and very high potential for groundwater springs covered 26% of the Nahavand Plain. The Root Mean Square Error (RMSE) for the training and validation datasets was lowest for the ANFIS-DE model compared to the other two models; and the ANFIS-PSO model had a higher convergence speed. These results may play an important role in sustainable groundwater management in the Nahavand Plain.

使用元启发式方法改进地下水潜力图

摘要 由于气候变化和城市发展,伊朗等缺水国家对新的淡水资源,尤其是地下水的需求正在增加。因此,本研究针对伊朗纳哈万德平原的地下水位图(GPM),在地理信息系统中使用优化的自适应神经模糊推理系统(ANFIS),采用三种元启发式优化算法:差分进化(DE)、粒子群优化(PSO)和蚁群优化(ACO)。使用 273 个泉水位置和 14 个地下水调节因子构建了一个空间数据库。使用接收器操作特性 (ROC) 技术评估优化算法。ANFIS-DE、ANFIS-PSO 和 ANFIS-ACO 模型的准确度分别为 0.816、0.809 和 0.758;地下水泉的高潜力和非常高的潜力覆盖了纳哈万德平原的 26%。与其他两个模型相比,ANFIS-DE 模型的训练和验证数据集的均方根误差 (RMSE) 最低;并且ANFIS-PSO模型具有更高的收敛速度。这些结果可能在 Nahavand 平原的可持续地下水管理中发挥重要作用。
