  1. INSTYTUT METEOROLOGII I GOSPODARKI WODNEJ PAŃSTWOWY INSTYTUT BADAWCZY INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT NATIONAL RESEARCH INSTITUTE TITLE : Progress Report of Task Team Leader on Potential Extreme Floods AUTHOR: Bogdan Ozga-Zieliński DATE: Third Meeting of RA VI Working Group on Climate and Hydrology 12-14 March 2013, Helsinki, Finland

  2. WORKPLAN: TT on PEF • Potential ExtremeFloods • Promote Guidelines for Flood Frequency Analysis – Long Measurement Series of River Discharge (to prepare new edition); • Prepare Report on River-flooding potential in terms of the safety of water management structures and flooding hazard - Introduction to methodology; • Prepare Report on Gradex-KC and Gradex-ZN methods for computing the maximum discharges with given probability of exceedence where discharge measurement data are incomplete; • Prepare Recommendation on design data for flood events; • Prepare Recommendation on best practices for flood monitoring, early warning and protection systems on local, national and international level; • Liaisewith EURAQUA Network.

  3. Nomination of experts to Task Team on PotentialExtremeFloods The following experts were nominated by their countries and accepted by 24 May 2010 (in alphabetical order): Rovshan ABBASOV (Azerbaijan) Dominique BEROD (Switzerland) Abdullah CEYLAN (Turkey) Eric GAUME (France) Giovanni BRACA (Italy) Thomas KJELDSEN (UK) Roman KONIECZNY (Poland) Bohuslava KULASOVA (Czech Republic) Rodica MIC (Romania) Jana PODOLINSKA (Slovakia) Donna WILSON (Norway)

  4. Promote Guidelines for Flood Frequency Analysis – Long Measurement Series of River Discharge (to prepare new edition) CD with new software for FFA

  5. Prepare Report on River-flooding potential in terms of the safety of water management structures and flooding hazard - Introduction to methodology

  6. Prepare Report on Gradex-KC and Gradex-ZN methods for computing the maximum discharges with given probability of exceedence where discharge measurement data are incomplete CD with software for Gradex-KC and Gradex-ZN methods, submitted to WMO as HOMS component

  7. Prepare Recommendation on design data for flood events THE METHODS OF RIVER DISCHARGE CHARACTERISTICS ESTIMATION – BEST PRACTICE HANDBOOK is in preparation. The cooperation with FLOODFREQ COST Action ES0901 European Procedures for Flood Frequency Estimation under WG-2: Assessment of statistical methods for flood frequency estimation was undertaken. Web site: http://www.cost-floodfreq.eu/

  8. Prepare Recommendation on design data for flood events The review of applied-statistical methods for flood-frequency analysis in Europe., Editors: Castellarin A., Kohnova S., Gaal L., Fleig A., Salinas J.L., Toumazis A., Kjeldsen T.R., Macdonald N., FLOODFREQ COST Action ES0901, http://nora.nerc.ac.uk/19286/, was published in year 2012, where Mr Bogdan Ozga-Zielinski was one of the co-authors.

  9. Prepare Recommendation on best practices for flood monitoring, early warning and protection systems on local, national and international level The research on the above subject was started but due to financial constrains of IMGW-PIB the work was limited and probably will not be finished in this inter-sessional period. For time being TT on PEF promote two publications on the above topic, namely Guidance on Flash Flood Management – Recent Experiences from Central and Eastern Europe issued by WMO/GWP Associated Programme on Flood Management (APFM) in 2007 and In Time for the Flood – A methodological guide to local flood warning systems issued by IMGW-PIB, GWP Central and Eastern Europe and APFM in 2005.

  10. Prepare Recommendation on best practices for flood monitoring, early warning and protection systems on local, national and international level

  11. Liaisewith EURAQUA Network At the 34 Management Board Meeting (MBM34) of EurAqua network, Madrid, Spain, 26-27 May 2010, the Terms of Reference of WGCH and Workplans of TT Leaders under Sub-group on Hydrology were presented by Messrs Markku Puupponen and Bogdan Ozga-Zieliński. During MBM35-39 Mr Bogdan Ozga-Zieliński presented work progress of WGCH and findings of RA VI Hydrology Forum 2012, held in Koblenz, Germany, 8-10 May 2012. TT Leader on PEF is the contact person of EurAquanetworkfor mutual collaboration with WMO. Web site: http://www.euraqua.org/
