On this webpage selected research projects are briefly introduced.
Value of radar-based data for flood modelling
Aim: This project explores the value of radar data for supporting flood modelling and flood predictions in Switzerland, as compared to the information acquired from a traditional rain gauge network. In particular, we analyse how radar-based precipitation products contribute to input and predictive uncertainty in flood estimates in a small fast reacting catchment.

MOOC (Massive Online Open Course): “Water in Switzerland”
Aim: The aim of the MOOC “Water in Switzerland” is to give a broad introduction to water in Switzerland. This includes an overview of the water resources and their spatial and temporal variation in Switzerland, the measurement of variables such as precipitation, snow, streamflow and groundwater, the use of water, water related hazards and the influence of water on society and culture. This MOOC will be open for anyone interested in learning more about “Water in Switzerland”.
Duration: July 2016 – 2018
Collaboration: Tracy Ewen (H2K), Jan Seibert (H2K), Ilja van Meerveld (H2K), Florian Lustenberger (H2K), Franziska Mohr (H2K)
Funding: MNF, University of Zurich

Hazard information for extreme flood events on the rivers Aare and Rhine (EXAR)
Aim: Provide a basis for assessing the hazard from extreme flood events on the Aare River (and, in a second phase, on the Rhine River). To this end, a number of statistical and model-based weather scenarios are developed and then evaluated with help of hydrological and hydraulic modelling.
Collaborations: Swiss Federal Institute of Technology in Lausanne (EPFL), Swiss Federal Institute of Technology in Zurich (ETH), Grenoble University, University of Bern
Sponsors: Swiss Federal Office for the Environment (FOEN), Swiss Federal Office of Energy (SFOE), Swiss Federal Nuclear Safety Inspectorate (ENSI), Swiss Federal Office for Civil Protection (FOCP), Swiss Federal Office of Meteorology and Climatology (MeteoSwiss)
Low flow and groundwater
In this project, we will quantify the sensitivity of Swiss catchments regarding droughts. Based on this quantification we determine a drought risk for the single catchment. For a better understanding of the role of the interaction between groundwater and surface water in the different catchments, we study how and when different catchment storages (e.g. aquifer) filter and buffer climatic variability and how the catchments might react on future changes in this variability.

Observing water availability in Switzerland
In collaboration between H2K and RSL this Innopool project aims at evaluating integration strategies for hydrological modeling and remote sensing of dynamic vegetation processes during water limited periods.

Climate change impacts on groundwater and low flow conditions in Switzerland
Aim: Impact of climate change on groundwater and drought in Switzerland, information and tools for managing water resources in Switzerland during low water situations.
Duration: November 2013 - October 2016
Collaboration: Jan Seibert (H2K), Philip Brunner und Daniel Hunkeler (University of Neuchâtel), Markus Weiler und Kerstin Stahl (University of Freiburg)
