Length in km as Wikidata records it (P2043, the best-ranked figure). Each named river counts on its own: the river that carries the name, from its source to its mouth. Headstreams and tributaries with names of their own are rivers of their own, so the Missouri and the Mississippi are two rivers here, as are the Irtysh and the Ob (the Longest River Systems set measures such chains as one system, from the most distant source). A named section of a river is that river: the Solimões, as the Amazon’s upper course is called in Brazil, is the Amazon. Where the recorded length runs from a differently named headwater (the Congo’s from the Lualaba’s source), the course is drawn on up that headwater. Rivers under 200 km are in only when they are well known (30 or more Wikipedia editions), and a river whose mapped course covers under half its recorded length is left out. Rivers in Antarctica are left out unless the quiz includes Antarctica. The Bay of Bengal basin: every river here whose waters reach the Bay of Bengal or a sea, gulf or bay inside it, as the IHO's sea areas nest (the North Sea lies in the Atlantic, the Adriatic in the Mediterranean), directly or through other rivers and lakes, following where Wikidata says each river flows (P403) downstream. Rivers of inland basins (the Caspian Sea, Lake Balkhash) reach no ocean.
