SUDPLAN – Sustainable Urban Development Planner for Climate Change Adaptation | Umweltbundesamt

With the "general service", SUDPLAN provides models for downscaling climate and environmental data for direct visualisation and as input data for local models. The global climate models ECHAM5, HADCM3 and CCSM3 are being used with emissions scenarios A1B and A2, the RCA3 regional model, the MATCH air quality model and HYPE for hydrology from the Swedish Meteorological and Hydrological Institute (SMHI).

The effects of extreme precipitation, flooding, air pollution, heat waves and storms will be analysed.

The models used in the pilot city of Wuppertal can satisfactorily simulate the surface drainage during a heavy rain event, allowing the influence of climate change on the frequency and intensity of future rainfall to be studied. This can be done using SUDPLAN's special web services. In addition, local construction measures to reduce flood risks (e.g. raising kerbs) can be run through in simulations. This makes use of the innovative visualisation options, which are capable of impressively portraying the effectiveness of these measures. This creates a good basis for the approval process with all affected decision makers and for advising affected property owners.

The Austrian case study examines adaptation measures for the sewage infrastructure in Linz to deal with more intense heavy rain events. In Prague, a planning tool will be developed to assess the city's impact on its surroundings and vice versa. This will be assessed using the environmental quality (air quality) and its influence on population migration from cities to suburbs or surrounding areas. In Stockholm, a planning tool will be developed to determine the air quality, incorporating the risks from exceeding national standard values and environmental targets for current and future climate scenarios.
