Pau Wiersma

PhD student (doctoral assistant) since 01.04.2021


In my PhD, I will use hydrological modeling to study the long-term effects of climate change on the hydrology of mountainous areas. The novelty of my research lies in the use of snow cover maps derived from synthetically generated remote sensing imagery of unobserved periods, such as in the past up until 1950 or in the future. Ideally, the vast increase in available snow cover maps will lead to better informed hydrological models, which in turn will increase our understanding on the effects of climate change on the hydrological cycle. If successful, this technique of synthesizing remote sensing imagery could be applied to other areas of geoscience as well.
