Inputs for Societal Decision Making

Integrating social-, natural- and engineering sciences

Decisions regarding the allocation and management of water resources, investment in water infrastructure and environmental protection almost always involve conflicting interests. Scientific input can help decision makers and resource managers anticipate the consequences of interventions. Socio-economic and policy analysis provides insight into the contexts in which decisions are made and implemented.

Eawag has studied how various pumped-storage hydropower scenarios affect temperature and water quality in the waterbodies concerned. In the case of Sihlsee, which serves as a reservoir for the SBB Etzelwerk plant, the question of withdrawal depth was found to be crucially important. The study also highlighted the fact that the assessment of environmental impacts largely depends on the definition of the reference state: whereas in natural lakes water is discharged from the surface, in reservoirs it is withdrawn from the lower layer. The environmental and aesthetic impacts of pumped-storage operations in the riparian zone were not examined in this study. Read more

Lagoons are valuable natural habitats as well as being good for tourism. In the case of the “Mar Menor” in the Spanish province of Murcia, however, such large quantities of nutrients are entering the unique ecosystem via the groundwater that algal blooms are making swimming impossible. Working together with Eawag, Spanish researchers have been modelling the underground water flows in order to develop better cultivation and water management scenarios. Read more
