  12. 12. BAD PROJECT• Project in Austria – Danube easterly from Vienna
  13. 13. WHAT ARE THE CONSEQUENCES?
  14. 14. - Stream down: sand, loam, clay, mud, limbs, also whole trees; all is deposited in Ba, Ču, Ga- 3 fresh water sources in Bratislava in danger (app. 800.000 inhabitants), Kolmatation- Old bridge will be relatively more low- Trees are dangerous for navigation- problems in locks (but also in weirs, WPP)- good only for the dark-green forces ☺- inacceptable for navigation
  15. 15. OLD BRIDGE, river km 1868,14 (Bratislava)
  16. 16. Bratislava, new flood protection wall
  17. 17. WPPS Gabčíkovo – Nagymarosengineers: good cooperation; politicians: bad cooperation

DEN HAAG, ICJ VERDICT:• Hungary was not entitled to suspend and later abandon in 1989 the works on the common Project,• Czechoslovakia was entitled to proceed in Nov. 1991 with the solution on his own territory, but was not entitled to put it into the operation in Oct. 1992,• The notification of Hungary of May 19, 1992, about termination of the Treaty, had no legal effect on the validity of the Treaty 1977,• Slovakia as successor of Czechoslovakia became the party in the Treaty 1977,• SK and H must negotiate in good faith, in the light of prevailing situation and must take all necessary measures to achieve the objectives of the treaty 1977, in accordance with such modalities, as they may agree upon,• A joint operational regime must be established and settlement of accounts for the construction and operation of works must be effected, both in accordance with the Treaty 1977, taking into account mutually agreed modifications,• If not agreed otherwise, both parties have to compensate to the other party, damages caused by their illegal conduct.
  21. 21. How to improve the cooperation on transboundary rivers• TbRCs members on high technical level (no politicians!),• To understand deeply the problems of all aspects of flood protection, to forecast (!) the problems,• Good administration – only one language in TbRCs• Enough money
