1. Introduction to research university projects Disaster 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 Cooperation Platform of Central and East European Metropolitan Universities of Technology Meeting Budapest, June 12-13, 2014

2. Outline of Research Framework 6 Four main themes Flooding Earthquake impacts 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 Floods leading to disaster Man-made damming

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

6. MISKOLC Flood-induced rural and urban inundation

8. Modelled inundation for disaster prevention planning

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

10. Industrial disastrous floods and their impact

11. Red mud spill in Hungary in 2010

12. Computer simulated spill and inundation process

13. 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

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

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

22. A modal shape analysis for earthquake resistant design

23. 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 Full-scale impact test Target damage Last example: Aircraft crash into NPP containment wall

25. 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
