Techno-economic study on the deepening and widening of the nav. channel in the maritime reach of the Congo River. A descripion of the hydro and sediment dynamics of the Congo River and the concept of morph. management to optimize the navigat. depth

In this report an overview is given of the available knowledge, tools and experience on the Congo river, especially near the zone of the “Région Divagante”, which were gathered over the course of the time. For the “Région Divagante”, which is the most critical region for navigation in the navigable part of the Congo river, an analysis has been performed on the following topics - hydrodynamics: description on annual hydrology, fresh water discharges, tides and currents - sediment : description of sediment characteristics and sediment transport - morphology : description on the morphology and its evolution - morphological management : description of basic concepts and applications
