- Abstract
River geomorphologic features along a 165-km stretch of the Luangwa River in eastern Zambia were assessed in 2008 to determine their influence on hippopotamus pattern of density distribution. A fixed high wing Cessna 206 aircraft fitted with geographical positioning system (GPS) was flown over the stretch taking coordinates for each geomorphologic feature, followed by taking length in metres of each geomorphologic feature on the ground. A total hippopotamus count was later carried out along the same stretch. Sixty-four geomorphologic features were recorded along the stretch of the river. Of the total geomorphologic features recorded, 34 (53%) were river bends, 13 (20%) lagoons and 17 (27%) were confluences. Hippo density was highest in river bends (75.48%), confluences (9.18%), lagoons 6.03% and all the other features put together had only 9.38%. It was concluded that geomorphologic features influenced hippopotamus pattern of density distribution in the Luangwa River.
