Short summary
This research explores different modelling approaches within a distributed and physically based hydrological model, emphasizing configurations that integrate groundwater recharge and dynamics. The study demonstrates that precise adjustments in model calibration can enhance the accuracy and representation of hydrological variables, which are crucial for effective water management and climate change adaptation strategies.
