フランス語:Voies navigables de France (VNF, (英語:Navigable Waterways of France)) is the French navigation authority responsible for the management of the majority of France's inland waterways network and the associated facilities—towpaths, commercial and leisure ports, lock-keeper's houses and other structures. VNF was established in 1991 and took over the responsibility for all waterways from the National Office of Navigation ((フランス語:Office National de la Navigation)) in 1993. It is a public body and is under the control of the Minister of Ecology, Energy, Sustainable Development and Territorial Development ((フランス語:Ministère de l'Écologie, de l'Energie, du Développement durable et de l'Aménagement du territoire)). The headquarters of VNF are in Béthune, Pas-de-Calais with local offices throughout France. The French natural and man-made waterways network is the largest in Europe〔(【引用サイトリンク】title=Waterways development )〕 extending to over of which VNF manages the navigable sections. The assets managed by VNF comprise of waterways, made up of of canals and of navigable rivers, 494 dams, 1595 locks, 74 aqueducts, 65 reservoirs, 35 tunnels and a land area of . Two significant waterways which are not under VNF's control are the navigable sections of the River Somme and the Brittany Canals, which are both under local management, and neither is the River Lot in Aquitaine. Approximately 20% of the network is suitable for commercial boats of over 1000 tonnes〔(【引用サイトリンク】title=Questions and Answers )〕 and the VNF has an ongoing programme of maintenance and modernisation to increase depth of waterways, widths of locks and headroom under bridges to support France's strategy of encouraging freight onto water as part of her sustainable development programme—a survey by Price Waterhouse Coopers showed that 75% of French companies were willing to switch to barge transport. A major current initiative is the cross-border Seine-Scheldt project which will provide a continuous wide-gauge navigation from Le Havre to Antwerp. ==See also== *List of rivers of France *List of canals in France 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Voies navigables de France」の詳細全文を読む スポンサード リンク
