Warning level (in swedish) 1, SwedenThe main tool is the conceptual HBV-model, originally developed at the SMHI in the 1970s. At present model development is focused on applications for climate change effect studies and non point source pollution. Related projects involve validation of internal model variables like evapotranspiration and snow cover. There is also an ongoing need for improved runoff forecasts. Several of the projects are carried out in co-operation with other research groups on a national as well as an international level.

Vizualisation of future climate and consequences for cities
A new production with visualization technology presents future climate and consequences for cities. Presentations of Urban Water Vision will be held in a Geodome at Stockholm Water Week.

Climate change affects groundwater
By the end of the century parts of Sweden will have higher groundwater levels, while levels in the south-east of the country may decrease sharply.

Scientific comparison of water quality models
Scientific comparison of water quality models
A unique scientific comparison of hydrological models to assess water quality is being carried out. The primary aim of the international study is to increase knowledge on uncertainties in model-based decision support.

Climate change a threat to sewage systems
Climate change a threat to sewage systems
Many cities could face problems with their sewage in the future. A research study for Stockholm shows that a change in precipitation, combined with a population increase, could bring disruptions as early as the middle of the century.

Workshop on snow modelling
The workshop was arranged at SMHI in January and started with a number of interesting presentations the first day. The second day the discussions were summerised in a white paper on snow modelling. The workshop saw participants from Sweden, Norway and France.

New service for European waters
Brand new opportunities for analysing water issues in Europe are now opening up thanks to a web service developed by SMHI. High-resolution information about water flows can be downloaded free of charge.

New research into water flows in a changed climate
How can climate change affect water flows, flooding and the transfer of nutrients via water? A far-reaching research project is set to develop a new generation of tools for hydrological climate impact.
New research into water flows in a changed climateInternational Review commend Swedish tools for water quantity and water quality assessment
A new calculation system for the Swedish water management recently received good grades in a scientific evaluation. The international panel of experts highlighted the tools that can serve as a model for other EU countries.
REVIEW OF THE SWEDISH NATIONAL MODELLING SYSTEM (76 kB, pdf)New climate tools for cities in Europe
City planners can access unique tools for adaptation to climate change. An extensive European partnership project will gradually offer help along the way. With new tools, city planners, for instance, will be able to create their own scenarios and case studies as the basis for making decisions on action to be taken. In many towns, there are already periodically huge problems with flooding. Climate change may make the situation even more extreme in the future.

The discharge of phosphorus is an important part of the puzzle for reducing eutrophication in lakes and seas. Phosphorus levels can increase significantly in connection with the spring flood. More measurements will improve knowledge.
Increased phosphorus discharges during spring floodSouth Africa in a warmer climate
Warmer and drier, as well as heavier rainfall. South Africa is one of the regions that will be affected the most by climate change. A new research report shows how the climate will change and how various areas of society can adapt to the new conditions.
South Africa in a warmer climateHYPE - a new hydrological model
The next generation hydrological model is under development and will successively be put into use. The model HYPE - HYdrological Predictions for the Environment - improves the estimation of factors connected to water resources and quality and allows the results to be presented with a very high level of geographical detail.
