Total length of waterways per country in kilometers
This is a list of waterways, defined as navigable rivers, canals, estuaries, lakes, or firths. In practice, and depending on the language, the term "waterway" covers maritime or inland transport routes, as suggested by "way". Wherever a free-flowing river cannot bear load-carrying vessels, the correct term is "watercourse", with no connotation of use for transportation of cargo. To be of practical use, the list distinguishes international maritime waterways (including ship canals), international inland waterways, then inland waterways, including canals and large lakes.
