  abstract = {{I}n the {C}ongo {B}asin, the elevated vulnerability of food security and the water supply implies that sustainable development strategies must incorporate the effects of climate change on hydrological regimes. {H}owever, the lack of observational hydro-climatic data over the past decades strongly limits the number of studies investigating the effects of climate change in the {C}ongo {B}asin. {W}e present the largest altimetry-based dataset of water levels ever constituted over the entire {C}ongo {B}asin. {T}his dataset of water levels illuminates the hydrological regimes of various tributaries of the {C}ongo {R}iver. {A} total of 140 water level time series are extracted using {ENVISAT} altimetry over the period of 2003 to 2009. {T}o improve the understanding of the physical phenomena dominating the region, we perform a {K}-means cluster analysis of the altimeter-derived river level height variations to identify groups of hydrologically similar catchments. {T}his analysis reveals nine distinct hydrological regions. {T}he proposed regionalization scheme is validated and therefore considered reliable for estimating monthly water level variations in the {C}ongo {B}asin. {T}his result confirms the potential of satellite altimetry in monitoring spatio-temporal water level variations as a promising and unprecedented means for improved representation of the hydrologic characteristics in large ungauged river basins.},
