Zambezi two largest left-hand tributaries of the Zambezi. The Kafue joins the main river in a quiet deep stream about wide. From this point the northward bend of the Zambezi is checked and the stream continues due east. At the confluence of the Luangwa (15°37' S) it enters Mozambique. The middle Zambezi ends where the river enters Lake Cahora Bassa (also spelled Cabora Bassa). Formerly the site of dangerous rapids known as Kebrabassa, the lake was created in 1974 by the construction of the Cahora Bassa Dam. The lower Zambezi's 650 km from Cahora Bassa to the Indian Ocean is navigable,
Subsurface flow where infiltration occurred, under the force of gravity or gravity induced pressures. Groundwater tends to move slowly, and is replenished slowly, so it can remain in aquifers for thousands of years. Mainly, water flows through the ground which leads to the ocean where the cycle begins again. Flow within the soil body may take place under unsaturated conditions, but faster subsurface flow is associated with localized soil saturation.* Subsurface flow Subsurface flow, in hydrology, is the flow of water beneath earth's surface as part of the water cycle. In the water cycle, when precipitation falls on the earth's land, some
