Topographic predictors of aquatic habitat suitability influence the spatial variation of vector density. A higher density is associated with concave planform curvature, particularly when located at the foot of steep slopes [78]

In the department of Dakar (i.e., the city centre), terrain is relatively flat, while in the suburbs, there is a succession of interdunal depressions that are prone to flooding [79]
