HGS RESEARCH HIGHLIGHT – A hybrid approach for integrated surface and subsurface hydrologic simulation of baseflow with Iterative Ensemble Smoother

[bmcneill]

This paper introduces the development of an integrated model for the South Québec region where low-flow processes are of primary concern. In this publication, HydroGeoSphere is used with a surface water mass balance module in order to reduce computational cost, enabling the use of mathematically rigorous, ensemble-based methods to support a calibration-constrained predictive uncertainty analysis.

This study is one of the first instances of a non-linear predictive uncertainty analysis for a regional scale and integrated surface and subsurface hydrologic model.
