Assessment of probable groundwater changes under representative concentration pathway (RCP) scenarios through the wavelet–GEP model

The main objective of this research was to evaluate the possible impact climate change on groundwater levels in Tasuj Plain, Iran. To accomplish this, values precipitation for a near future period projected through four general circulation models (GCM). Then, level variations genetic expression programming (GEP) model were evaluated. projection results indicated that average annual with 33.55 mm base would decline 20.51, 20.11, and 19.14 under three representative concentration pathway (RCP) scenarios, namely, RCP2.6, RCP4.5, RCP8.5, respectively. determination coefficient range from 0.92 0.99; root mean square error between 0.12 0.61, absolute 0.08 0.54 showed forecasting GEP model, all have acceptable results. evaluation simulation demonstrated developed previous performs better. Prediction based scenarios Plain at beginning experience gradual reduction then increase very slightly end period. Overall, it found declining has no significant impacts other parameters like anthropogenic activities could be primary reason depletion.
