Erosion of the slopes of the Kiel Canal
In order to enhance the attraction of the Kiel Canal for large vessel shipping, the BMV today: BMVBS, planned to modernize and improve conditions for traffic passing through the canal. A coordinating body made up of key canal users and service providers under the auspices of the WSD North is to pool all measures for upgrading the Kiel Canal and monitor traffic development on an on-going basis.
Through the WSD North, in December 1997 the BMV arranged for WSA Brunsbüttel to be responsible for commissioning the Hamburg office of the BAW to investigate the current erosion conditions and make recommendations for handling traffic in future.
The study programme drawn up in early 1998 by the WSA and BAW included among others:
- Systematic investigation into ship-induced hydrodynamic loading of the Kiel Canal from current traffic including encounter and overtaking manoeuvres
- Field measurements of ship-induced hydrodynamic and geotechnical loading of the unprotected underwater embankments in the Hohenhörn section of the canal where there is a high risk of erosion, using amongst others high-resolution fan-type echo sounding measurements
The results and recommendations of the studies in the hydraulic model for determining ship-induced loading in the Kiel Canal provided among others the basis for evaluating the provisional introduction of encounter number 8 (sum of the traffic group numbers) from the point of view of hydraulic engineering.
An extensive field measurement programme at Kiel Canal km 26.06 in cooperation between WSA Brunsbüttel and the Kiel Canal pilots association was followed by corresponding evaluation and recommendations based on the hydraulic model and field measurements.
