Brings real-world examples to learning.
Svenja Fischer is an Assistant Professor in the Hydrology and Environmental Hydraulics group at Wageningen University & Research, Department of Environmental Sciences, a position she assumed in February 2024. She obtained her master's degree in mathematics from Ruhr University Bochum and her Dr. rer. nat. in statistics from the Technical University of Dortmund in 2017. In 2021, she completed her habilitation on "Consideration of Deterministic Hydrology to Improve Flood Statistics for Extreme Floods" at Ruhr University Bochum's Chair of Engineering Hydrology and Water Resources Management, receiving the Tison Award from the International Association of Hydrological Sciences for her publication "Timescale-based flood typing to estimate temporal changes in flood frequencies." From 2017 to 2024, Fischer held postdoctoral and project leadership roles at Ruhr University Bochum's Institute of Hydrology, including as coordinator and project manager for the DFG-funded research unit SPATE in Civil and Environmental Engineering.
Her research centers on stochastic hydrology, with primary interests in flood statistics, flood type analyses, process heterogeneity in environmental statistics, and the combination of stochastic and deterministic modeling to quantify uncertainties in flood-generating processes. She also studies low flows and droughts through process stratification and mixture models. Key contributions include her book "Type-Based Flood Statistics: An Interlink Between Stochastic and Deterministic Flood Hydrology" (Springer, 2023), and papers such as "Dominant flood types in Europe and their role in flood statistics" (Hydrological Sciences Journal, 2025), "Multivariate Flood Frequency Analysis in Large River Basins Considering Tributary Impacts and Flood Types" (Water Resources Research, 2021), "A statistics-based automated flood event separation" (Water Resources Research, 2020), and "Generation of type-specific synthetic design flood hydrographs" (Journal of Hydrology, 2023). With over 1,100 citations and more than 30 publications, her scholarship impacts flood risk assessment and hydrological modeling. Fischer was Vice-President of the IAHS International Commission on Statistical Hydrology (2019-2023) and serves as Associate Editor for Hydrological Sciences Journal, Journal of Hydrology, and Hydrologie und Wasserbewirtschaftung. She teaches courses including "Water Systems: Analysis," "Environmental Data Collection and Analysis," and "Catchment and Climate Hydrology."
