Technical-Biological Bank Protection on Inland Waterways
Within a joint research project, the Federal Waterways Engineering and Research Institute (BAW) and the Federal Institute of Hydrology (Bundesanstalt für Gewässerkunde, BfG) are investigating for the first time the applicability of technical-biological bank protection measures along waterways with regard to technical, ecological and nature conservancy aspects.
The long-term objective is to provide the planning staff of the Federal Waterways and Shipping Administration (WSV) with well-founded principles and recommendations on the use of this type of bank protection measures along German federal waterways.
Since the EU Water Framework Directive (WFD) came into effect in 2000, ecological aspects have become more and more important in new constructions and development measures along German federal waterways. Technical and ecological aspects also need to be considered for maintenance measures. This means that technical-biological bank protection measures should be applied more frequently as a more environmentally friendly alternative than ordinary riprap revetments. However, only little experience and no codes and guidelines exist so far for their use along waterways.
Therefore, studies on the hydraulic load-bearing capacity of technical-biological bank protection measures have been carried out for several years, taking into account the impact of navigation; furthermore studies on the ecological potential of these construction methods have been undertaken. The aim has been to develop application recommendations and dimensioning principles for their use along German federal waterways.
