| Summary: | A meta-analysis on 192 peer-reviewed articles reporting on applications of the
variable infiltration capacity (VIC) model in a distributed way reveals that
the spatial resolution at which the model is applied has increased over the
years, while the calibration and validation time interval has remained
unchanged. We argue that the calibration and validation time interval should
keep pace with the increase in spatial resolution in order to resolve the
processes that are relevant at the applied spatial resolution. We identified
six time concepts in hydrological models, which all impact the model results
and conclusions. Process-based model evaluation is particularly relevant when
models are applied at hyper-resolution, where stakeholders expect credible
results both at a high spatial and temporal resolution. |
