Wei Liu

Integrated surface–subsurface hydrological models are essential tools in integrated water resources management. During his studies, Wei Liu has worked with the development and application of a state-of-the-art surface-subsurface hydrological model SWAT-MODFLOW, which he combined with empirically based models for relationships between stream flow regime and indices representing taxa-specific stream biota.

The project has resulted in a greater understanding of groundwater-surface water interactions, and how diversely these may influence stream biota. The novel approach of combining SWAT-MODFLOW and flow-biota models can be a highly useful tool for assessing the effects of groundwater abstractions and climate change on stream biota and thereby potentially support water planning and regulations related to groundwater abstractions and climate adaptation.

The PhD degree was completed at the Department of Bioscience, Faculty of Science and Technology, Aarhus University.
