Not only the current severe weather conditions in Germany make clear that flood protection is a not insignificant task for the federal government, cities and towns.
In order to meet the threats of heavy rain events, innovative solutions are needed which combine new with proven technologies to create an effective and lasting protection against floods. In carrying out such a construction project ecological aspects have to be considered, without losing sight of the requirements of the shipping and tourism industries.
That this balancing act has been particularly successful in the planning and construction of the Rees flood channel is proven by the Working with Nature-Award that has been granted by the PIANC (The World Association for Waterborne Transport Infrastructure) 2014 in San Francisco.
In her workshop "Flood Protection - Ecology and Technology" the International Geotextile GmbH presented the products used in this building project against the backdrop of the Rees flood channel. Among the materials utilized are for example the iGGmat Vmax P550 and the iGGgab river matrasses.
Subsequently Dr. Volker Seidel (Ökon Vegetationstechnik GmbH) and Thomas Roess (International Geotextile GmbH) presented Xylit as an effective way for water purification.
With an area of approximately 215,000 square meters where hydroseeding has been used, of course this topic could not be neglected. Holger Neisser (International Geotextile GmbH) presented the functioning of the FiNN HydroSeeders and explained amongst other things how extreme locations such as immature soil embankments can be treated.
Peter Kleine (construction manager, WSA Duisburg-Rhein) and Gerd Niedzielski (ecological supervision, Ingenieurbüro Landschaft und Siedlung GbR) provided the participants in the afternoon with the practical insights of what was talked about in theory in the morning during a ferry ride into the flood channel. Peter Kleine was very happy with the successful completion of the construction works and the wide acceptance of the flood channel by the local community. He also pointed out the huge interest of other Waterways and Shipping Administrations for this project and the materials and technologies used.
