The Luena River of Zambia's Western Province rises just west of the Kafue National Park and flows west through Kaoma to become a tributary of the Zambezi.
In the wet season the Luena Flats flood and overflow into the Ndandu channel or floodplain which leads south-west to the Barotse Floodplain of Zambezi north of Limulunga and Mongu.
[citation needed] In the dry season, vehicle tracks cross the Luena/Ndandu floodplain between north and south, allowing a direct route between Mongu and Lukulu and North-Western Province, Zambia.
In the wet season the floodplain is impassable and vehicles have to travel west towards Kaoma, then north-west on the Kaoma-Lukulu road.
At the height of the flood this road also becomes impassable across the floodplain, and there is no practical alternative.
