Abstract
Abstract. This study investigates the effectiveness of various calibration approaches within the Water Balance Simulation Model (WaSiM) to enhance the representation of hydrological variables. We assess the impact of three distinct configurations: Baseline (BL), Physical Groundwater Model (GW), and Physical Groundwater with Recharge Calibration (GW-RC) on the representation of hydrological variables. The analysis demonstrates that while traditional calibration primarily enhances streamflow prediction, integrating recharge and groundwater dynamics significantly refines the model’s ability to depict subsurface processes. The GW-RC configuration, with minimal emphasis on recharge in the objective function, shows a marked improvement in representing both the spatial and seasonal variability of groundwater recharge, suggesting that even small and targeted calibration adjustments can significantly enhance the accuracy and realism of model outputs. Although this approach may reduce the model’s flexibility in mirroring observed streamflow, it enhances the precision with which other hydrological processes are represented, providing a more accurate reflection of watershed dynamics. Our findings underscore the importance of multi-variable calibration frameworks, which incorporate both streamflow and internal hydrological variables, in developing robust models capable of adapting to anticipated hydrological shifts due to climate change. This approach provides a more accurate reflection of watershed dynamics and offers valuable insights for calibration strategies in hydrological modelling, water resource management and climate adaptation strategies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
