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
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
Some relevant past and ongoing research projects
Rivers and floodplains
Natural conditions
Floods leading to disaster
Man-made damming

Flood-induced rural and urban inundation
MISKOLC
Flood-induced rural and urban inundation
Modelled inundation for disaster prevention planning
What if a thousand years return period
flood wave arrives in River Danube at Budapest
Industrial disastrous floods and their impact
Red mud spill in Hungary in 2010
Computer simulated spill and inundation process
Computer simulated spill and inundation process
Impact assessment of various prevention measures
Soil mechanics aspects of earth dam construction:
Pore water changes in the construction and operation period
Lab and computer simulated drift of solid bodies by floodwaves
Impact of dam break flood waves on buildings
investigated in lab by PTV analysis
Downstream environmental impact of the red mud spill
Downstream environmental impact of the red mud spill

Full-scale test:Sugano et al. 1993, New-MexicoF4-Phantom fightervelocity: 215 m/s7×7×3.66 m reinforced concrete blockaircraft 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
HORIZON2020 outlook
