  1. Cooperation Platform of Central and East European Metropolitan Universities of Technology Meeting Budapest, June 12-13, 2014 Introduction to researchuniversityprojectsDisaster prevention:up-to-date engineering methods Prof. János Józsa Head, Department of Hydraulic and Water Resources Engineering Vice-Dean for Science, Faculty of Civil Engineering

  2. Outline of Research Framework 6 Four main themes Flooding Earthquakeimpacts Disastrous environmental pollution Industrial security, fire and explosion All relevant in disaster prevention and management, with a lot of links to each other

  3. Some relevant past and ongoing research projects

  4. Rivers and floodplains Natural conditions Man-made damming Floods leading to disaster

  5. Flood-induced rural and urban inundation MISKOLC Szirmabesenyő Sajó Sajókeresztúr

  6. Flood-induced rural and urban inundation MISKOLC Alsózsolca Felsőzsolca Auchan Sajó MISKOLC

  7. M30 Új bekötőút Felsőzsolca

  8. Modelled inundation for disaster prevention planning

  9. What if a thousand years return period flood wave arrives in River Danube at Budapest

  10. Industrialdisastrousfloods and theirimpact

  11. Red mud spill in Hungary in 2010

  12. Computer simulated spill and inundation process

  13. Computer simulated spill and inundation process Impact assessment of various prevention measures

  14. Soil mechanics aspects of earth dam construction: Pore water changes in the construction and operation period

  15. Lab and computer simulated drift of solid bodies by floodwaves

  16. Impact of dam break flood waves on buildings investigated in lab by PTV analysis

  17. Downstream environmental impact of the red mud spill

  18. Downstream environmental impact of the red mud spill

  19. Bridges to resist earthquakes Pentele bridge over Danube in Hungary Total length: 1780 m Span (arch) : 307.8 m Height: 48 m, cross-section: steel box(~2 x 3 m)

  20. Bridges to resist earthquakes Megyeri bridge over Danube in Hungary Total length: 1862 m Span (cable-stayed bridge) : 300 m Pylon height: 100 m

  21. A modal shape analysis for earthquake resistant design

  22. Last example: Aircraft crash into NPP containment wall Full-scale impact test Finite element model • ANSYS, explicit dynamic analysis • harmonization of the parameters of FE model and real aircraft • simplified aircraft geometry for parametric studies • target structure: circular shell • aim: determination of important input parameters • broken elements are deleted from the calculation Full-scale test: • Sugano et al. 1993, New-Mexico • F4-Phantom fighter • velocity: 215 m/s • 7×7×3.66 m reinforced concrete block • aircraft was totally crushed (debris dispersed) • penetration did not occur (concrete cover was damaged) • aircraft crushed only at the cross-section adjacent to the target Target damage

  23. HORIZON2020 outlook Two relevant submitted applications: PFM-WATER – Monitoring of Particle-laden Fluxes for more efficient use of Water 21 partners from all over Europe, leading by Bologna DREAM-CO – Danube River Research and Management Coordination Action 34 partners, leading by BOKU, Vienna
