6th International Workshop on Design and Construction of Final Repositories "Backfilling in Radioactive Disposal", Brussels
(August 2002)
The Groundwater Protection and Waste Disposal department recently contributed a scientific publication in Brussels. The poster's topic is the "Three-dimensional simulation of the desaturation and resaturation of a hypothetical repository in a deep clay formation".

Flood Protection: From the Concrete Wall to the Fascine
(July 2002)
| In recent years the newly constructed houses along the river Bünz in Othmarsingen have been flooded several times resulting in quite heavy damage to cellars and gardens. The authorities therefore decided to implement a flood protection and re-naturation project, which was executed by Colenco in 1998. Following another flood in May 1999, the design, then in its final stages, was adapted to the latest findings.
Construction began a few months ago with detailed design and supervision carried out by Colenco. The variety of works to limit flood protection on one hand and re-naturation aspects on the other demands the support of various specialists as well as creative construction techniques.
Under normal conditions, concrete walls are constructed to protect houses and surroudings from flooding. As for the re-naturation areas, new methods and materials are being used in order to conserve fauna and flora. One example being large bundles of brush wood, which after being anchored into the riverbank, will in time either take root and flourish or rot. |
