3 History of the project 2002: Decision of the Austrian Hungarian water commission to develop a flood warning system for the Raab river March 2007 in Szombathely (Hungary): agreement for a common approach for the development of a flood warning system for the Raab based on the structure of the Mur model as bilateral EUproject May 2008: Submission of the Application form to the Joint Technical Secretariat (JTS) of ETZ - programme Austria - Hungary August 2008: Approval of the project by the JTS April 2009: Signing of contract with Joanneum Research/ Danish Hydrological Institute April 2011: Finalization of the Austrian part of the system End of 2011: Finalization of the whole system including Hungary

4 Key facts Project partners: Lead Partner: Government of Styria, Department 19A Other partners: Government of Burgenland, Department 9 Contractors: Water directorate of Szombathely Water directorate of Györ Austria: Joanneum Research (Graz) and Danish Hydrological Institute (Denmark) Hungary: Danish Hydrological Institute and TU Budapest EU-programme: ETC Austria - Hungary Costs of the whole project: ~ 1.4 Mio Euro Duration:

5 Description of the system Raab catchment Catchment area total ~ km² Austria ~ km² Hungary ~ km²

6 Description of the system Structure Hydrometeorogical data Meteorological forecasts Austri a Sloven ia Hunga ry Croati a Austria Central server in Graz Automatical calculation of forecasts for 6 days in advance Local systems Calculation of scenarios Homepage Visualisation of forecasts

7 Description of the system Models Forecasting Model MIKE Flood Watch Rainfall Runoff Model NAM 2000b Hydrodynamical Model MIKE 11

8 Description of the system Structure: Data assimilation The simulation is updated to match the measured flow Simulated Updated Observed Time of Forecast

9 Description of the system Outputs and results Webpage: water level and discharge Actual status and deterministic forecast for each gauge graphically table

10 Description of the system Outputs and results Webpage: other results

11 Experiences, problems and solutions Planning phase Decision about the model structure Austria Hungary Austria Austria Option 1: two seperated system with data interface at the border central server local server Austria Option 2: 1 central server for the whole catchment and 4 local servers

12 Experiences, problems and solutions Development phase Seperated model development in Austria and Hungary Caused by delayed undersigning of the subsidy contract between leadpartner and EC Austria started with model development at own risk, Hungary had to wait for signed contract Consequence: seperated procurement and development phase of the models Two models were merged together in central server end of 2011

13 Experiences, problems and solutions Operational phase Data exchange between central and local servers

14 Experiences, problems and solutions Operational phase Handling with results Styria: results of central server for selected gauges are published at an official homepage of the department 14 Burgenland: results of central server for selected gauges are published at the homepage of the hydrografy together with online gauges Szombathely: results of local server (without data assimilation) are published at a homepage for experts Györ: results of central server for selected gauges are published at the official homepage 2 times a day

15 Experiences, problems and solutions Operational phase Maintenance and updating of the system Expert meetings (all partners): 2 times a year were experiences with model results as well as wishes for updates in the central server are discussed Online documentation of changes in the models: at the ftpserver of Styria, all updates (i.e. new calibration, new stations etc.) in the models are documented with version number Updating and calibration of the models: continuous process (new calibration after flood events, new cross profiles, new structures) Maintenance: 3 year warranty for Hungarian partners with DHI, in the future new warranty contract has to be signed

16 Summary and outlook Flood forecasting system for Raab catchment is running operationally since 2012 Central server 4 local servers Flood forecasting models are vital systems, you have to work with and try to improve it continuously With the used system structure, a permanent and intensive collaboration between all partners is necessary

17 Summary and outlook Project ProRaab(a) 2 (based on funds not allocated in the actual ETC programme period): update of the flood forecasting model (MIKE CUSTOMIZED) for central and local servers including INCA data (rainfall forecasts) for Hungary Project ProRaab(a) 3 (next ETC programme period): connection to the results of 2-D flood studies (flood inundation zones) catalogue system Connection between rainfall scenarios and flood inundation zones (catalogue system) Civil defence exercises based on the catalogue systems
