Investigation of extreme floods in Hungary
concerning IMPACT project
László Nagy National Water Authority,
Budapest, Hungary
Where we are ?
Carpathian Basin
Inundation map
Hungarian Answer
Carpathian Basin
Duna-valley in the Carpathian basin 547 dike failures
Tisza-valley in the Carpathian basin 1269 dike failures
WP 2: Breach formation
The Hungarian party is going to contribute:
•Investigation and report of dike failures in the past 200 years in the Carpathian basin (statistical datas of breach mechanism, lenght, etc.)
•Contribution and expertise on the earlier breaches e.g. Tarpa breaches in 2001.
Levee breach, River Tisza right bank, Tarpa - Tivadar section, 54+650 and 55+350 tkm
Total volume of water flowed out through the two breaches were
120 - 140 million m3

Origin of the flood causing failure
Levee breach, River Tisa right bank, Tarpa - Tivadar section, 54+650 and 55+350 tkm
WP 3: Flood propagation:
The Hungarian party is going to contribute:
•Propagation of inundation in protected flood plain basin as a consequence of levee failure,
•Expertise on the earlier inundations e.g. Tarpa breaches in 2001.
