River training works research to improve navigation conditions on the Elbe River close to the Czech/Germany border

Original language description

Proposal river training adjustments of the Elbe River in the form of channel dredging and the realization of longitudinal training dams (LTDs) is the part of the project to improve navigation conditions between the city of Ústí nad Labem (CZ) and the Czech / German state border. The research was carried out by the 100 m length physical hydraulic model in 1:70 scale. In this section, the composition of LTDs and channel dredging has been optimised with regard to sediment transport, navigation and environmental conditions around spurs and flood risks in the floodplain. Part of the research was also the verification of the deformations of the river bed for various flows, which was evaluated by means laser scanning technology. Navigational conditions were tested on the model using nautical experiments with radio-controlled cargo ship models. An important aspect of the proposed adjustments is to maintain appropriate environmental conditions for plant communities. For this reason, the LTDs design was verified using another 1:50 hydraulic model. The aim of the research was to ensure the hydraulic conditions between the LTDs and the shore, which ensure the sustainability of the gravel banks and do not allow the space to be filled with fine particles. Since 2009, research on seven experimental LTDs has also been carried out in the area of interest. This research verifies the function of experimental LTDs on a 1:1 scale by hydraulic, morphodynamic and biological monitoring. The results of measurements so far confirm the conclusions of previous researches.
