Outflow: Well Pumpage GW System Inflow: Natural Recharge; Incidental AG Recharge; Treated Effluent Recharge GW System Outflow: Groundwater discharge (baseflow); EVT and Underflow

▼ Outflow: Well ▼ Pumpage ▼ GW System Inflows: Natural Recharge; Incidental AG Recharge; Treated Effluent Recharge Model is Calibrated by matching water levels, ▼ , and baseflow targets ≈ . The calibration process is described in detail and is transparent in ADWR model report. GW System Outflows: Groundwater discharge (baseflow, ≈ ); EVT and Underflow
