Short Summary

This commentary highlights a methodological challenge in edge-of-field runoff prediction and demonstrates the importance of event-centered evaluation when developing EOF prediction models. The study shows that training strategies tailored to datasets dominated by non-runoff days improve runoff event detection.

Objective

• Investigate the effectiveness of the Ford et al. (2022) hybrid modeling and regionalization framework for edge-of-field runoff prediction in the Great Lakes region.

Study Configuration

• Spatial Scale: The study focuses on the Great Lakes region.
• Temporal Scale: The study examines event detection at a daily time scale.

Methodology and Data

• Models used: National Water Model (NWM) outputs, machine learning algorithms.
• Data sources: Cluster analysis, satellite data, observation data, reanalysis data.

Main Results

• Training strategies tailored to datasets dominated by non-runoff days improve runoff event detection.
• The inclusion of additional soil and meteorological information provides further improvements while maintaining reasonable overall accuracy.

Contributions

• This study highlights the importance of event-centered evaluation when developing edge-of-field prediction models, providing original insights into the limitations of accuracy-based evaluation in rare event scenarios.
