Water Disasters in Hungary made by: Debreceni Egyetem Kossuth Lajos Gyakorló Gimnáziuma és Általános Iskolája Debrecen, 2017.

Floods in Hungary In the Hungarian Great Plain’s large area there is no natural drainage . About one quarter of the country is exposed to floods, which is exceptional in Europe. Flood dykes of 4200 km length protect 700 settlements, 2.5 million people, 2000 industrial plants and indirectly about 30% of the GDP. Flood protection has been successful in the past, but recently the Tisza Basin has exhibited new signs of increasing risks: peak flood levels show a clearly increasing trend. The reasons are : -land using changes -climate alterations -- flood plain bed should be added. -further increases in peak water level are anticipated . Niki Kathi and Johanna Lakatos

One of the most serious floods of Central-Europe was in Hungary in 2013. Flood disasters in Hungary: Flood of Pest 1838: In 1838 on the watershed area of the river Danube the amount of precipitation was high. In March there came a huge ice drift and a sudden flood. Flood of Szeged 1879: In March Tisza river broke into Szeged due to THE bursting of a dam. It swallowed most of the city, caused terrible damages and killed 151 people.

Summer flood on Danube 1954: It started in July due to the bursting of a dam as well. Water flooded the whole Szigetköz. Tisza river 1970: In the 20th century one of the greatest floods of Tisza river started in April. Flood on the river Danube 2002: In August over the watershed area of Danube there formed a huge cyclone full of moisture. This formation was enclosed by 2 anti-cyclones and therefore a great amount of moisture fell. to the ground. Spring flood on both Tisza and Danube 2006: This flood was so special because it is rare that floods start on Tisza, Danube and their affluents at the same time. Dávid Böttkös

What was the red sludge? The red mud-like industrial byproduct was being held in a containment pond owned by the Hungarian Aluminum Production and Trade Co. The byproduct is produced when bauxite rocks are processed to make aluminum. The wall collapsed and released a toxic torrent that swept cars off roads . Farmland soil had to be removed and replaced . The dried sludge is also toxic . Niki and Johanna

2000 Baia Mare cyanide spill The 2000 Baia Mare cyanide spill was a leak of cyanide near Baia Mare, Romania, into the Someş River by the gold mining company Aurul. The polluted waters reached the Tisza and then the Danube, killing large numbers of fish in Hungary and former Yugoslavia. The spill has been called the worst environmental disaster in Europe since the Chernobyl disaster. Large quantities of fish died due to the toxicity of cyanide in the waters of the rivers, affecting 62 species of fish, of which 20 are protected species. In Hungary, volunteers participated in removing the dead fish to prevent the disaster from spreading across the food chain, as other animals, such as foxes, otters have died after eating the toxic dead fish.
