River hydrodynamics studies in the Congo Basin inform global and regional issues pertaining to biogeochemical cycling, ecology, water resource availability and flood risk. These studies rely increasingly on measurements from satellite that are limited by resolution, coverage and uncertainty, and their inability to directly measure bathymetry or discharge. We obtain new in-situ data covering 650 km of the Congo’s main stem, including elusive bathymetry and discharge measurements that compliment space-borne datasets. However, our key findings relate to our water surface elevation measurements. These show that spatial coverage of existing satellite altimetry for deriving river water surface profiles is adequate through the globally important Cuvette Centrale, but not at its outlet where our field data reveals significant spatial variability in water surface slope. The findings have implications for altimetry-based hydrodynamics studies of the Congo and other large rivers, such as studies that involve estimating discharge or modelling multichannel river hydraulics.
