This book presents a regularly updated inventory of existing and envisaged standards and parameters of E waterways (Pan-European network of inland waterways of international importance) and ports in Europe and shows, on an internationally comparable basis, the current inland navigation infrastructure parameters as compared to the minimum standards and parameters prescribed in the European Agreement on Mainland Inland Waterways of International Importance (AGN). It identifies bottlenecks and missing links in the existing E waterway network. This 3rd revised edition has just been prepared by the UNECE Transport Division in accordance with the instructions of member States.
