The above map contains information on limitations on waterways which have been provided via Notices to Skippers as well as the bottleneck service (shallow/narrow sections) implemented on the Danube corridor. Zoom-in and click on points for more information.
Additional note for the bottleneck service on the Danube:
The least sounded depth information from the riverbed sounding is converted into a maximum allowed vessel draught in order to be considered as network impact in the voyage calculation. This least sounded depth information represents the most shallow spot within the fairway of the bottleneck section.
