Extremely heavy rainfall in large parts of Eastern Europe resulted in disastrous floods on the river Oder in the Czech Republic, Poland and Germany. In many places the highest floodwater levels exceeded those previously recorded. The flooding in Germany was also exceptional because of its long duration. This documentation shows the course of events in the German disaster zone, gives an impression of the complexity of the protective measures and provides political and technical conclusions drawn from the Oder flooding for the future. Furthermore, the video explains the hydrological, geographical and historical background of the affected German Oder region and gives information about damage to technical high water protection systems and its prevention.
