UNH/GRDC: Estimated River Runoff

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:

  • Statistical 'best estimate' of terrestrial runoff over large domain

Key Limitations:

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