The Leibniz University of Hannover together with the University of Stuttgart assessed the uncertainties that arise when applying a complex modeling chain for predicting reservoir sedimentation under changing climate. The modeling chain consists of the water balance model WaSiM, the soil erosion and sediment transport model combination RUSLE-SEDD and the 3d hydro-morphodynamic reservoir model SSIIM2. In order to assess the propagation of uncertainties throughout the modeling chain, approximate model parameter uncertainties were quantified and compared to the uncertainties originating from climate models, which were represented by the spread of the climate projections (considering 3 GCM and 3 RCM). The results show that the model parameter uncertainties are much smaller than the spread of climate projections and are important not only for DIRT-X, but also for other modelers who would like to communicate different sources of uncertainty in complex modeling chains, including climate impact models,

Do you work with water resources, e.g. hydropower, food agencies or in a water- or environmental authority? Would you like to know more about how the changing climate and socioeconomic conditions may influence water reservoirs and the services they provide to different economic sectors? Then join us in March for a 3-part webinar series where findings from the EU project DIRT-X will be presented!

The Webinars:

  1. Climate impact indicators and insights for hydropower from interconnected energy systems: A pan-European perspective (March 2nd, 14:00-15:00 CET)
  2. Hydrological climate services and ecological impacts: insights from a coastal use case (March 16th, 14:00-15:00 CET)
  3. Hydro-climatic change and sediment dynamics: Insight from two hydropower use cases (March 23rd, 14:00-15:30 CET)

Your key takeaways:

  • Learn more about how reservoirs are affected by sediment, now and in a future climate, and how this may affect your type of operations.
  • Discover the world of climate impact indicators, and how they can be useful for cross-sectoral assessments

Get in touch with the DIRT-X team during the Q&A, and support the future content and development of water- and climate services for your sector!

The webinars are held online in English and are free of charge.
