 The definition for scientific purposes has been proposed as “seasonally waterlogged, predominantly grass covered, depressions bordering headwater drainage lines”.The problem with the preceding definition is that the word may also be used for wetlands bordering rivers far from the headwaters, for example the dambo of the Mbereshi River where it enters the swamps of the Luapula River in Zambia, .A 1998 report of the FAO distinguished between ‘hydromorphic/phreatic’ dambos (associated with headwaters) and ‘fluvial’ dambos (associated with rivers), and also referred to five geomorphological types in Zambia’s Luapula Province
