Modelling the impact of large impoundments on the Lower Zambezi River

What is it about?

The study of the morphological evolution of the Lower Zambezi River downstream of the Kariba and Cahora Bassa dams was made by means of a 1-D mathematical model. The main aim of the research is to explain of a changing water flow can alter the morphodynamics of a river in terms of sediment transport and cross-section shape. The use of simplified 1-D models permits the study of remote areas using only a few input data.

Why is it important?

This research contributes to the evaluation of the impact of two large impoundments in one of the major African rivers, located in a remote area. Moreover, this study shows the reliability of 1-D models in describing the long-term morphological evolution of watercourses at basin scale.
