A new tool for automatic baseflow separation

Base flow represents the groundwater contribution to river flow. Its estimation is of overwhelming importance in hydrological modeling and water resource management, particularly during low flow periods. We propose a new automatic procedure to calibrate a filter used for deriving base flow from measured river flow. The method operationality and robustness is demonstrated for a broad range of catchments.

This study results from a cooperation between our group anf the group of "Hydrogéologie et géologie de l'environnement". It was published this month in Water Resources Research: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2018WR023351.
