FAIRway Danube II is a transnational project with the involvement of Austria, Slovakia, Hungary, Croatia, Bulgaria and Romania that aims to increase the fairway conditions on the Danube and make inland navigation more climate resilient, sustainable and attractive. Planned tasks and objectives are: (1) Implementation of regular transnational monitoring of fairway conditions, (2) Procurement of sensors for measuring water levels, fairway depths and bridge clearance heights, (3) Upgrading the national waterway management systems (WAMS) and the transnational waterway monitoring system (WAMOS 2.0) to increase their performance and efficiency and to improve information provision to users, (4) Extending the lead time of water level forecasting – a key tool for logisticians, (5) Testing flexible infrastructure elements in Austria, Croatia, Romania and Bulgaria. This unique approach will provide a non-invasive, near natural solution for low water periods, as it can be used to flexibly influence fairway depth. In this way, the reliability of inland navigation will be improved without any permanent impact on habitats and ecosystems. (6) Modernization of existing mooring places in Austria and Romania to improve infrastructure, especially in terms of crew safety and mobility. The work also includes green energy solutions for shore power at each mooring place. Plans are also being developed for additional investments in mooring places in Austria, Slovakia and Croatia.
