Over the next decades, environmental and societal changes are expected to affect many aspects of water quality like nutrient, toxicant and fine sediment concentrations. In order to minimize the negative impacts on the ecological status of running waters, iWaQa aims at developing and testing a decision support framework for Integrated River Water Quality Management that allows for evaluating management alternatives under conditions of environmental and societal change. The practical relevance and innovation potential of the approach will be demonstrated in two catchments in the Swiss Plateau, in close collaboration with the municipal and cantonal authorities.The scientific focus of iWaQa, embedded into the overarching decision support framework, is on exploring the link between water quality and the ecological status of streams. As a core element, we will develop a Probabilistic Network Model (PNM), which will integrate the relevant knowledge in a formal framework to assess the outcome of different management options. The submodels incorporated into the PNM are both existing simulation tools and novel models currently being developed in on-going Eawag projects. Water quality will be treated comprehensively including nutrients, toxicants and fine sediments. The ecological effects of possible changes in water quality will be assessed by taking into account expected changes in flow and temperature regimes of the streams. iWaQa is an ambitious and highly interdisciplinary project, which brings together scientists from ecology, environmental chemistry, engineering and systems analysis as well as regulators and water managers. Due to the limited duration, it will build to a large extent on existing knowledge complemented by data from a 1 year field campaign in both study areas.Clearly, our main focus is related to sustainable water resources management (module 2 of NRP 61) but there are strong ties to hydrological processes (module 1) and to socio-economic aspects (module 3). Thus, iWaQa will yield insight how integrated management approaches can be enhanced by improved theoretical frameworks, better understanding for specific processes and broader data availability. From a practical point of view the project will give insight which water quality issues may be of major concern in the future and guide the involved stakeholders to ensure a good ecological status in aquatic systems.
