Gasper Laurent Sechu studied and digitally mapped how streams and groundwater interact in river valleys and how that affects water and nutrient transfer coming from upland areas.

The new research findings contribute to understanding how water and nutrients are transferred in river valleys, and the digital maps created can be used as decision support tools for managing stream pollution.

The PhD study was completed at Department of Agroecology, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
