Short Summary

The study evaluated the HEC-HMS model for ungauged basins, revealing significant variability in initial abstraction (IA) across three catchments, thus emphasizing the need for site-specific IA assessment for accurate hydrological modeling.

Objective

• To assess the potential of HEC-HMS as a transferable modeling tool for ungauged basins in data-limited regions, specifically evaluating the impact and appropriate estimation of initial abstraction (IA) values.

Study Configuration

• Spatial Scale: Catchment scale (three distinct catchments).
• Temporal Scale: Not specified in the provided text.

Methodology and Data

• Models used: HEC-HMS (Hydrologic Engineering Center - Hydrologic Modeling System)
• Data sources: Available site-specific information (details not provided).

Main Results

• Initial abstraction (IA) values exhibited notable variability among the three studied catchments.
• The assumption of a uniform IA value across different catchments was found to be inappropriate.
• A preliminary assessment of IA using available site-specific information is crucial for approximating realistic values.
• The HEC-HMS model shows potential as a transferable modeling tool for ungauged basins in data-limited regions, provided that key hydrological parameters are carefully evaluated prior to application.

Contributions

• Challenges the common assumption of uniform initial abstraction (IA) in hydrological modeling, highlighting the necessity of site-specific assessment.
• Provides support for the transferability of the HEC-HMS model to ungauged basins in data-limited contexts, contingent on rigorous parameter evaluation.
