The river Congo is exceptional in more ways than one: it is the second longest river in Africa behind the river Nile (4,700 km), it is also in second place (behind the river Amazon) in terms of its flow and river basin, and it irrigates the second largest tropical rainforest in the world. Thus, it represents a formidable opportunity for the development of river navigation on the river Congo itself and its tributaries.
The presence of natural obstacles does not allow continuous navigation on its entire length, but the medium pound between Kisangani and Kinshasa, which measures 1734 km, does not feature a single waterfall; thus, it represents a very interesting waterway for navigation and does not require many developments, if any. In addition to this pound, a significant section of its main tributary, the river Kasaï, can also be taken into consideration.
In this context, Arteila is in charge of updating the navigation maps for 2,300 km of rivers between Kinshasa and Kisangani and the river Kasaï between the river mouth (Malela-Kwa) and Ilebo. This update is based on crossing navigation constraints depending on the types of boats considered and the hydraulic parameters obtained through a one-dimensional model of the river Congo.
The largest convoy considered has the following characteristics: 1,200 tonnes, 255 m long, 24 m wide, 2 m draft.
