For centuries, urban dwellers have tended to settle on fertile lands and floodplains, simply because living conditions there seem more convenient than elsewhere due to proximity to water and food resources. In the Democratic Republic of Congo, this phenomenon is highly visible along lotic hydrosystems, including the Ndjili and Kalamu rivers in the city of Kinshasa, and the Kalamu River in the city of Boma. Conversely, the same waterways that provide life to surrounding inhabitants pose the threat of cyclical and severe flooding. Moreover, intense activities carried out within the areas comprising the hydrographic network repeatedly expose it to multiple ecological problems: sedimentation, narrowing of main channels, reduced flow, pollution, etc. In the face of this dramatic and drastic phenomenon, it is worth noting that very few efforts are made for large-scale maintenance, functional management of waterways, or their proper sanitation. As a result, almost all rivers in Kinshasa and Boma are rarely managed or dredged. Sediment accumulation in riverbeds is observed in all rivers, causing overflows and flooding in urban areas, leading to significant human and material damage during heavy rains or downpours.
