Zambezi Watercourse Commission Mozambique and flowing to the Indian Ocean. 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. The eight Zambezi Basin riparian states that participate in ZAMCOM are Angola, Botswana, Malawi, Mozambique, Namibia, Tanzania, Zambia and Zimbabwe. ZAMCOM operations are in line with the revised SADC Protocol on Shared Watercourses. The SADC Protocol was adopted in 1995 and by SADC member states, including all Zambezi riparian states, and came into force in 1998. Seven of the riparian states signed the ZAMCOM Agreement on 13 July
Bottom water in temperature and salinity, especially compared to wind-driven surface ocean currents. The bottom water of the Arctic Ocean is more isolated, due to the topography of the Arctic Ocean floor and the surrounding Arctic shelves. Bottom water by an estuary of a river discharging into a saline body exhibits peculiar transport of mud. Due to fresh/saline water intermixing by the estuary, a horizontal isohale gradient is created, with lower salinity levels upstream, which generates the upstream flow of the bottom water. Mud particles carried by river begin settling down as the current and turbulence decrease. When the particles nearly reach
