Predicting of the Climate-induced Depletion in Groundwater Level and Storage: A case in Akarçay Basin

In this study, we examined the potential impact of climate change on depletion groundwater levels and storage. To achieve so, simulated flow using HİDROTÜRK hydrogeological model under projections considering RCP4.5 RCP8.5 scenarios. estimate forcing input (recharge evapotranspiration) for model, used precipitation temperature outputs from two Global Circulation Models, namely HadGEM2-ES MPI-ESM-MR. assess changes in level storage, applied our experimental design Şuhut alluvial aquifer Akarçay Basin (Turkey). The study revealed that there is not necessarily a substantial difference tracked over estimated between scenarios until end 2050s. Yet, significant reduction hydraulic head (approximately 114 m) storage (-17.25 %) – particularly western part expected 2100, according to RCP8.5. This confirmed selected only leads different predictions depletion, yet also results degree confidence simulations.
