Excessive use of water resources in combination with climate change threaten to significantly reduce groundwater arid and semiarid regions. We studied the effects on level for important Dehgolan Aquifer northwestern Iran. The this aquifer has dropped by about 35 m during last 30 years. Soft computing techniques were used together projections three methodological steps estimate drop 2045. Firstly, MODFLOW was simulate flow movement. Secondly, simulation results, support vector regression (SVR), least-squares SVR (LSSVR) machine learning models predict levels future 20-year period (2026–2045). whale optimization algorithm (WOA) improve prediction results optimizing parameters. Thirdly, CMIP6 (ACCESS-CM2, BCC-CSM2-MR, CMCC-ESM2) changes precipitation (2026–2045) using SSP 2.6 8.5 scenarios. showed that MODFLOW-LSSVR model predicted more accurately than MODFLOW-SVR MODFLOW-SVR-WOA. calculation scenario containing previous month level, monthly withdrawal, had highest performance predicting root mean square error (RMSE), absolute percentage (MAPE), Nash Sutcliffe efficiency (NSE) equal 0.305 m, 0.014 0.998, respectively. indicate may decrease (about 6% compared reference 1987–2005). This decrease, along continuation current will cause a 36 (during 28 years) (1.3 per year). reveal could be reduced 12 adopting 25% reduction withdrawal. findings show necessity providing suitable management approach prevent exhaustion due withdrawal situation region.
