Global Calibration of Distributed Hydrological Models for Large-Scale Applications
Publication: Journal of Hydrologic Engineering
Volume 18, Issue 6
Abstract
Large-scale distributed hydrological modeling is nowadays more widely applied for water resource management. To ensure the spatial consistency of distributed parameters, an alternative calibration strategy is suggested: the global calibration. This approach aims to identify a single parameter set suitable for every stations located within the modeled domain. A global calibration procedure is applied and tested over a large portion of the St. Lawrence River basin () using Hydrotel, a physically based semidistributed hydrological model. Despite limitations in estimating high flows on small catchments, global calibration is regarded as a fair trade-off between local performance and regional consistency of parametric information. In the near future, the global calibration strategy will act as a key methodological framework for large-scale hydrological assessments.
