Short Summary

This study compares two rainfall-runoff models, SWAT+ and IHACRES, in the Setail Watershed, Indonesia, to investigate parameter transferability between contrasting flow regimes.

Objective

• Investigate whether a model ranking established during calibration survives a change in flow regime

Study Configuration

• Spatial Scale: Catchment scale (278.43 km²)
• Temporal Scale: Monthly time step from January 2006 to December 2025

Methodology and Data

• Models used: SWAT+ (semi-distributed, process-based) and IHACRES (lumped conceptual)
• Data sources: Observed discharge record at the Kradenan gauge, Thiessen-weighted areal rainfall series derived from eight rain gauges

Main Results

• Both models showed a decrease in performance during validation compared to calibration, with SWAT+ retaining 83% and IHACRES retaining 74% of its calibrated R² values
• The study found that parameter transferability between contrasting flow regimes is limited, highlighting the need for model-specific calibration

Contributions

• This study provides new insights into the limitations of parameter transferability in rainfall-runoff models, contributing to a better understanding of hydrological modeling in tropical catchments

Funding

• Not specified
