Threat of mining and damage floods on River Tisza: Between catastrophes and management
Schulz, Erhard; Tittizer, Thomas
The series of damage floods in River Tisza since 2000 and the mining disasters in NW-Romania in 2000 showed exemplarily the reaction of a river as a whole. A cooperationproject between the Geographical Institutes of Würzburg and Cluj, Federal Institute of Hydrology BafG/Koblenz, the Institute for Plant Sciences Graz and the State Museum of Natural History Lviv shall elucidate the historical development of the pollution and consequences for human health in the north-eastern catchment area of River Tisza. Basic information for an adapted river management shall be provided. The first results concerning the heavy metal pollution and its history show that a remarkable pollution only started with the establishment of the central lead- and copper-smelters in the 18th and 19th century. The landscape development since led to an accelerated vulnerability of the region, which may be enlarged furthermore by high-risk mining projects. This reveals the necessity of a holistic approach in river management. The Tisza River is an outstanding example for this holistic approach.
