Abstract

Les amémagements des cours d'eau ont été responsables d'un considérable affaiblissement de la valeur écologique de systèmes fluviaux dans les régions alpines d'Europe. Dans ce contexte, la morphodynamique des confluences alpines améagées est étudiée expérimentalement, avec une attention particulière sur Ie potentiel d'un élargissement local de I'affluent en cas de renaturation des confluences. Les résultats montrent qu'un élargissement local de I'affluent augmente la variabilite sédimentaire du substrat ainsi que la diversité de la profondeur et des vitesses d'écoulement. Cette réponse est favorable au développement des habitats et au rétablissement de la connectivité latérale et longitudinale des réseaux fluviaux. L'élargissement offre un grand potentiel d'amélioration du statut écologique, aussi bien localement qu'à I'échelle du bassin versant. Desurcroit, ce gain lié I'élargissement n'est pas assorti d'effets contraires concernant la protection contre les crues.

Democratic Republic of the Congo

The Democratic Republic of the Congo (DRC), also known as Congo-Kinshasa and formerly known as Zaire, is a country in Central Africa. By land area, the DRC is the second-largest country in Africa and the 11th-largest in the world. With a population of around 112 million, the Democratic Republic of the Congo is the most populous officially Francophone country in the world. The national capital and largest city is Kinshasa, which is also the economic center.

Kinshasa

Kinshasa (kɪnˈʃɑːsə; kinʃasa; Kinsásá), formerly Léopoldville, is the capital and largest city of the Democratic Republic of the Congo. Once a site of fishing and trading villages situated along the Congo River, Kinshasa is now one of the world's fastest growing megacities. The city of Kinshasa is also one of the DRC's 26 provinces. Because the administrative boundaries of the city-province cover a vast area, over 90 per cent of the city-province's land is rural in nature, and the urban area occupies a small but expanding section on the western side.
