However we are still facing unforeseeable disasters, there is no possibility to leave seashores and riversides as the places of peoples activity of any time. Also there is no chance to implement everywhere more or less sophisticated systems of anti disaster preventions, mostly because of fi nancial shortages. But the other problem is lack of understanding that more important than prevention is so called “cooperation with water”. Such an approach is a part of sustainable development, and is creating safe conditions for any waterside localisation.
