The PIANC INCOM WG 141 was founded in 2010 to provide planners of inland waterways with design standards for inland vessels in accordance with those for sea-going vessels, worked out e.g. by PIANC MARCOM WG 49. It came out that the MARCOM approach seems generally not applicable for inland waterways, especially because of the better steerability of inland vessels, the lower ship speeds and the lower damages in case of accidents. Additionally special design aspects that scale the necessary waterway dimensions in inland areas have to be considered such as the strong influence of cross flow or the visibility conditions. So, a new design method will be recommended, especially for fairway width in canals and rivers, bridge openings, diameters of turning basins or the length and width of lock approaches. In so far eight meetings, two interim meetings on special questions, a workshop within the framework of the Smart Rivers Conference last year and several internal workshops, the group finished the review of existing guidelines. It analysed several best practice examples, especially concerning fairway design in rivers, the dimensions of lock approaches and bridge openings. Presently a first draft of the future guidelines will be worked out, basing mostly on the contributions to the Smart Rivers Conference 2013 and the present paper, which includes these papers with some additions according to the agreements of the last meeting in February of this year. So, the paper provides information on the working group process and the actual findings. In more detail, the three recommended design steps: “Concept Design Method”, “Best Practice Approach” and “Detailed Design” will be demonstrated by examples. As for all design cases the existing, possible future or necessary safety and ease of navigation conditions have to be assessed or defined. For this WG 141 provides planners with an appropriate approach, depending on the ship type, ship speed and traffic density as well as the local boundary conditions to be considered.
