“…In downstream samples from Dresden and Torgau, also high amounts of DDT can be found indicating impact from the same source. High DDT concentrations (> 1.5 mg/kg) were also reported recently for Elbe sediment sampled near the Czech Border [15], which was attributed to a leaking deposit of waste of chemical production in the Czech Republic. The concentrations of organic tin compounds are 10-fold increased in samples downstream of river Mulde as compared to upstream samples.…”

During the river Elbe flood in August 2002, large amounts of suspended organic matter were transported and settled in the course of the river. The aim of this study was to assess the quality of river Elbe sediments using chemical and biological methods. For this purpose 11 samples from river Elbe and 2 from tributaries were investigated. Two contact biotest systems, used to identify the ecotoxic potential of sediments, showed toxic effects in all sediments. Exposure was assessed by quantification of priority pollutants; however, no causal link to biological effects could be established. Effect qualities were characterised by testing organic sediment extracts in a biotest battery consisting of 8 test systems. Test systems varied in sensitivity to detect effects in the samples. Furthermore, samples differed in their ecotoxic potential. An effect‐directed analysis was conducted in order to identify compounds responsible for the biological effects. Cause‐effect relationships were established for mixtures of polycyclic aromatic hydrocarbons being partially responsible for toxic effects on algal reproduction; however the majority of the cause for toxicity remained unclear. Overall, it has to be concluded that Elbe sediments are not in accord with current quality goals. The chemical and the biological transect profile of the sediments indicate toxicant inputs from Czech Republic, river Mulde and diverse source.

“…The frequency and intensity of natural disasters emerged over the last decades ( Berz 1999 ). Recent examples are the flooding in Middle Europe in 2002 and 2005 ( Gutknecht et al 2002 ;Ehret and B á rdossy 2002 ;Grunewald et al 2004 ) or Hurricane Katrina and Hurricane Andrew in the US ( Baade et al 2007 ). All of these aforementioned occurrences lead to heavy economic and personal losses ( Benner et al 2002 ;Frei 2006 ;Baade et al 2007 ), but also required substantial disaster response including several organizations with each having a huge number of relief workers employed During the last flood in Europe, the Bavarian city called " Passau " saw the second highest water levels since record-keeping began in the 14th century ( Daller 2013 ).…”

Over the past decades, an increasing number of environmental situations posed threats to humans and assets. Natural disasters happen more frequently and with higher intensity -such as floods caused by heavy rains. One example was the flood that hit in the middle of Europe in 2013. This article reports a single case study of the flood in the German city of Passau in 2013. In the case study we analyze the governance structure employed throughout the flooding as well as how it was managed. Beyond this, we examine how information and communication technology supported the management staff in fulfilling their tasks. Data were collected through semi-structured qualitative interviews with members of the management staff from the main organizations involved in the relief work for the Passau Flood in 2013. Our results show that a hybrid governance structure was employed. All in all, the disaster could be averted, but we identified several challenges and areas for improvement, which could be helpful for managing future disasters successfully.
