Visualization of climate change and challenges for city planning

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.

More rain with increasing intensity presses big demands on how to plan cities for the future. How can the water volume be handled? And how can science support with knowledge?

Visualization technology makes it easier to see and understand things that are extremely complex. Presentations of future urban hydrology will be held at Stockholm Water Week, in a Geodome, that permits 25 visitors at a time.
 
Presenters from the Swedish Meteorological and Hydrological Institute will lead through a 15-minute visualization.

- A very intense rain which today occurs on average once every 20 years would in the future occur every 6-12 years. The increasing amount of water means that city planners already today have to consider increased risks, for example flooding, says Jonas Olsson, researcher hydrology.

- But rainfall has large spatial variation, and the local effects are often essential for the strategies of adaptation to a changing climate.

Climate researchers are developing mathematical models with higher resolutions, to better capture the geographical variations. Global models are downscaled to regional and local level.

Urban Water Vision is produced by the Swedish Meteorological and Hydrological Institute in cooperation with Vizualisation Center C in Norrköping. Contributions to the production come from Formas (project Hydroimpacts), Mistra (project Mistra-SWECIA), and EU FP7 (project SUDPLAN).

The presentations are taken place at the World Water Week, Stockholm, T-area, Sunday Aug 21th- Thursday Aug 25th from 10 am to 5 pm.

Workshop

Researchers from SMHI are also participating in a workshop during World Water Week, “Adapting Cities to Climate Variability and Change”, arranged August 24th.
