During three years there have been continuous activities on dissemination of results from the Swedish research project HYDROIMPACTS2.0, including dialogues and outreach to stakeholders and end users. Besides the traditional dissemination towards the academic community (e.g. scientific papers and conference contributions), the project included various web-based tools to facilitate hydrological climate change impact assessment as […]

According to the future scenarios from global and regional climate models, the climate change will profoundly affect hydrological processes at different scales in time and space. This paper presents results from a new generation of hydrological climate change impact studies, combining new methods for downscaling and bias correction of climate projections with new methods for […]

Two climate projections are used as forcing data in a hydrological model for the Lake Mälaren catchment, in order to evaluate the expected impact on nutrient fluxes (nitrogen and phosphorus) into the lake. Lake Mälaren comprises a large lake system, discharging into the Baltic Sea through the city of Stockholm, Sweden. Being a major fresh-water […]

Hydrology is strongly precipitation-dependent and hence hydrological modeling and forecasting requires accurate precipitation input for good performance. Hydrological climate change impact assessment thus requires good estimates of future precipitation. Climate modeling is the main means of estimating future precipitation, but it is seldom possible to directly use the precipitation output from climate models for meaningful […]

Pollutant transport in the unsaturated soil zone is a potential threat to surface and ground water resources. The intensity and volume of rainfall are the parameters that decide how fast and deep the pollutants will be transported. Climate models predict a future rainfall climate with higher total volume and higher intensities. In the present study […]
