At TU Dresden, Faculty of Environmental Sciences, Department of Hydro Sciences, the Institute of Groundwater Mangement offers, subject to the availability of resources, a position as Research Associate / PhD Student in Hydrological Modeling (m/f/x)
(subject to personal qualification employees are remunerated according to salary group E 13 TV-L)

starting September 1, 2022, limited for 3 years with 75 % of the full-time weekly hours and the option of increase. The period of employment is governed by the Fixed Term Research Contracts Act (Wissenschaftszeitvertragsgesetz – WissZeitVG). The position offers the chance to obtain further academic qualification (e.g. PhD).

Background: The position is part of the work of the DFG research group “Fast and Invisible: Conquering Subsurface Stormflow (SSF) through an Interdisciplinary Multi-Site Approach” and in the project “SSF MODEL BENCHMARKING: Towards a robust parameterization of SSF in hydrological models at the catchment scale† located. In close cooperation with the Institute of Geographical Sciences, FR Applied Physical Geography, Free University of Berlin, the capabilities of lumped distributed hydrological models for the simulation of SSF processes in the four catchments of the research group are to be investigated. Hydrological models are standard tools in both basic hydrological research and in applied water management.

Their development, calibration and the subsequent assessment of their performance are mostly based on gauged discharge time series, which represent the sum of all hydrological sub-processes occurring in the catchment (surface runoff, intermediate runoff or SSF, groundwater runoff). An assessment and evaluation of individual simulated sub-processes has so far hardly been possible due to the lack of separate measurement data, which in turn leads to great uncertainties in the modeling of the sub-processes including SSF.

The aim of the project is therefore to identify the potential of novel SSF proxy data, which are collected by the research group from its various projects, to optimize model calibration and reduce uncertainties when mapping SSF in existing model systems.

Tasks: setting up existing lumped hydrological models for four study areas in Germany and Austria, evaluating the models by sensitivity and uncertainty analyses, identifying potential for reducing model uncertainties and deficits in model architectures and mathematical process descriptions, application of the models for improved quantitative recording of SSF under different meteorological conditions. In addition, field work to support the data collection in the experimental catchment areas in cooperation with the other projects of the research group as well as the collection of model-relevant parameters on site.

Requirements: university degree (e.g. MSc.) in hydro or environmental sciences, environmental engineering, hydro(geo)logy, physical geography, or comparable; very good degree, high motivation and fun in interdisciplinary scientific work as well as special interest in hydrological modeling and the inclusion of experimental hydrological data in the modeling process; experience in modeling and programming; knowledge of model evaluation using sensitivity and uncertainty analysis using various observation data; very good knowledge of English is expected; knowledge of German and a class B driving license are desirable, but not mandatory.

We offer: Participation in an exciting, highly topical and interdisciplinary research project at the interface between experimental hydrology and hydrological modelling. You will work in an international team at the Institute of Groundwater Management in close contact with the postdocs and PhD students of the research group at various universities in and outside of Germany; attractive working conditions and further training opportunities at the Technical University of Dresden; flexible working hours and the opportunity to combine family and career.
