Project summary

Changing climate, forest disturbance and stream modifications are the most significant drivers of runoff regime alterations in mid-latitude mountain catchments. Rising variability of runoff response, prolonged periods of drought, and changes in seasonal runoff distribution emerge as the key symptoms. However, the observed changes are complex and have different scope and magnitude in different environments.

The goal of the Ph.D. research project is the attribution of the effects of climate change and the landscape alteration on runoff response in mid-latitude montane catchments with a focus on extreme events - peak flows and droughts. The research will be carried out at different spatial scales, ranging from the small experimental catchments, equipped with the own sensor network monitoring and requiring field monitoring, to the complex basins with long-term observations. The attribution of the drivers to the given aspects of hydrological change will be done mostly using geostatistical analysis and modeling.

The proposed Ph.D. research will require skills in hydrological analysis and/or modeling, interest in learning new approaches, the ability of teamwork as well as independent research. Motivated students from geographic, hydrologic, or geoscientific disciplines with scientific curiosity and relevant skills are encouraged to apply.
