The Zambezi basin also includes parts of Malawi and Tanzania. The Zambezi is the fourth largest river in Africa after the Nile, Congo and Niger. Functions of the ZRA, as laid out in the acts that created the body, include: The
Castlereagh River travel the distance, and up to 47 hours. Usually in peak floods, the greater the water volume, the faster the travel times of the peak. However, the flattening of the terrain upstream of Coonamble results in decreased flow velocity (but means a greater area for the flow is needed to avoid flooding). It is not correct that the Castlereagh River is an underground river (subterranean river) or an 'upside down' river. However, water that once was in the river bed on the surface does flow through the extensive sands under the riverbed. This water is therefore part of the underground
