Day 4. Danube Excursion: Linz—Krems

by Stefan Bitsch


Linz → Hütting → Grein → Melk → Krems


Dangers of the Danube: Floods and Rapids throughout History

On the fourth day of our excursion, the group had the opportunity to learn from Christian Rohr (University of Bern) and Severin Hohensinner (University of Natural Resources and Applied Life Sciences in Vienna), who shared their expertise with us during the various stops along the way.

Hütting and the Machland Dam

The first series of stops were concentrated around the small town of Hütting, part of the longest connected dam-building program in Central Europe, which cost around €180 million and was completed in 2012. Forty-five kilometers of dams and flood retention areas now follow the course of the Danube in this region. The area has a long history of flooding, and the town has learned how to deal with these events over time.

Interview: Lise Sedrez on the Samarco Tailings Dam Spill, Minas Gerais, Brazil (Part One)

The mine tailing dam break in Bento Rodrigues, Mariana, Minas Gerais, Brazil, on 5 November 2015 has been described by the Brazilian government as the country’s worst environmental catastrophe. Robert Emmett and Claire Lagier sat down with Brazilian environmental historian Lise Sedrez at the RCC in Munich on 19 November and recorded the following interview.

RE: Those of us who don’t read Portuguese have to rely on what the media in English is saying. I’m curious about the language used to describe the event. I like to think “Let’s start with the facts,” but of course that’s exactly what is up to debate. I read that some seismic activity was recorded?

LS: I just don’t buy that one. If we go for the facts, let’s say that Brazil is on a very old tectonic platform. We used to say “There [are] no natural disasters in Brazil,” which of course is not true. There have been very few cyclones. We had one in Santa Catarina [in 2004] and it was like “Oh my God, that never happens.” The last time something like this happened was about 170 to 200 years earlier. But there are no earthquakes. What they registered was seismic activity between 1 and 2 on the Richter scale. We had larger seismic activity in Minas Gerais in the past, with no effects whatsoever. And there is a strong possibility that this recorded  seismic activity happened as a result of the breaking of the dam.
