Waterway Coverage is the total available distance of usable water lanes internally accessible to any one nation. Access to such routes allow for movement of various goods when and where serviceable roads and railways prove limiting. In peacetime, waterways are critical to shipping and general economic health. In times of war, they provide warplanners with routes for movement of man, machine and supplies to critical fronts.
Values below displayed in Kilometers (km). For the purposes of the GFP ranking, some nations report 0 km of useful waterways (ex: Qatar) while others showcase no value whatsoever (ex: Israel). These values are per the CIA World Factbook.
