UNH/GRDC: Estimated River Runoff

UNH/GRDC: Estimated River Runoff
Main content

Combines observed river discharge information with a climate-driven Water Balance Model in order to develop composite runoff fields that are consistent with observed discharges. This combination preserves the accuracy of discharge measurements as well as the spatial and temporal distribution of simulated runoff, providing a 'best estimate' of terrestrial runoff over large domains.

Key Strengths

Key Strengths

Statistical 'best estimate' of terrestrial runoff over large domain

Key Limitations

Key Limitations

Model-based estimate (but constrained by observed river discharge)
