摘要

•Systematic study for assessing uncertainties in hydrologic data assimilation.•Incorrect definition of model uncertainty can lead to poor assimilation performance.•Assimilation performance is robust to a large range of uncertainty magnitudes.•Innovation statistic is a useful diagnostic to evaluate uncertainty estimation.
